Opinion

Affirmed by unpublished opinion. Judge WILKINSON wrote the opinion, in which Judge DAVIS and Judge COGBURN joined.

Unpublished opinions are not binding precedent in this circuit.

WILKINSON, Circuit Judge:

Tanya Valencia Mack challenges her conviction for conspiring to distribute and to possess with intent to distribute cocaine in violation of 21 U.S.C. §§ 841(a)(1) and 846 on various grounds. In particular, she argues that the district court erred in (1) admitting expert testimony regarding the use of coded language on government wiretaps, (2) allowing a prosecution witness to mention a utility bill for Mack’s residence, and (3) refusing to define “reasonable doubt” in its jury instructions. For the reasons that follow, we reject these challenges and affirm Mack’s conviction.

I.

A.

In January 2008, the Harford County Narcotics Task Force (“Task Force”) began to investigate an alleged conspiracy to distribute cocaine involving Mack, as well as her sister, Candis Unita Mack (“Can-dis”); her brother, Winston Charles Mack (“Winston”); and her boyfriend, Fernando Alexander Settles (“Settles”). As part of its investigation, the Task Force obtained authorization from the Circuit Court for Harford County, Maryland, to intercept telephone calls placed to and from all the conspirators’ mobile telephones, including Mack’s. Between January and March 2008, the Task Force intercepted thousands of calls, some of which contained coded references to cocaine and the narcotics trade.

*361 The Task Force also conducted visual surveillance of Mack and her coconspira-tors. For example, on one occasion, Task Force members observed Mack meeting with one individual, whom the police stopped shortly thereafter, discovering cocaine in his vehicle. Task Force members also observed Mack regularly coming from and going to a particular house in Abing-don, Maryland, which they concluded was Mack’s residence. Indeed, after the police discovered 250 grams of cocaine on Settles’s person during a traffic stop and arrested him for cocaine possession, the driver of the vehicle in which Settles had been travelling called Mack to say that he and Settles had been on their way to the Abingdon house to see Mack when they were pulled over.

Based on the intercepted calls and the surveillance, the Task Force obtained a warrant to search the Abingdon house. The Task Force executed the warrant on March 5, 2008, recovering the mobile telephone on which Mack had made and received the intercepted calls; a digital scale with cocaine residue; inositol, a cutting agent; and baking soda. Mack was present during the search, and the Task Force arrested her at its conclusion.

A federal grand jury indicted Mack— along with her sister, brother, boyfriend, and a fourth codefendant — on one count of conspiring to distribute and to possess with intent to distribute fifty grams or more of cocaine base and 500 grams or more of cocaine powder in violation of 21 U.S.C. §§ 841(a)(1) and 846.

B.

Mack was tried before a jury in the U.S. District Court for the District of Maryland. At trial, the prosecution called as an expert witness Detective Sean Marston, a member of the Task Force who had participated in the investigation of Mack and her coconspirators. Specifically, the prosecution offered Marston “as an expert witness with regard to the methods and practices of drug traffickers and drug conspiracies, with regard to quantities, packaging, prices, and distribution of controlled substances, as well as the interpretation of coded phone language and conversations that occur over wiretaps.” To establish his qualifications as an expert on these topics, Marston testified that he had served as a police officer for more than thirteen years; that he had previously served as a task-force officer assigned to the Drug Enforcement Administration; that he had monitored wiretaps dozens of times, listening to thousands of drug-related conversations in the process; that, as a result of his experience, he was familiar with the code words and phrases used by narcotics dealers and purchasers; that he had served as an affiant on the wiretap applications for the telephones used by Mack and her coconspirators and had listened to thousands of their telephone calls; and that the judge presiding over Mack’s trial had previously accepted him as an expert in interpreting coded drug-related conversations in the joint trial of Mack’s brother and boyfriend.

Although Mack’s trial counsel did not object to Marston’s testifying as an expert on the general practices and methods of the drug trade or on the details of the distribution of narcotics, he did object to Marston’s testifying as an expert in interpreting coded drug-related conversations. Mack’s counsel noted that Marston had taken only “high school English, high school Spanish”; that he was “not a linguist”; and that he was “not a cryptographer or a cryptologist.” The district court overruled this objection, deeming Marston adequately qualified as an expert in interpreting coded drug-related conversations *362 based on his extensive experience with the drug trade.

As the prosecution proceeded to play recordings of a number of the intercepted telephone calls for the jury, Marston identified various words and phrases on the recordings as coded references to drugs or the drug trade. For example, after learning that the police had seized one kilogram of cocaine from Candis during a traffic stop, Mack had called another relative to discuss Candis’s arrest, and at one point during the conversation, the phrase “the majority” was used. Marston construed this phrase to mean that Mack had contributed most of the money that had been used to purchase the seized kilogram of cocaine. In another intercepted call, Mack instructed Winston to obtain baking soda and to “cook six plates of food,” which Marston interpreted as a reference to six ounces of crack cocaine. The jury also heard conversations between Mack and unidentified callers in which the phrases “both kind” and “playing hard, hard, playing basketball” were used. Marston interpreted the first phrase as a reference to powder and crack cocaine and the second as a reference to 3.5 grams of cocaine.

In cross-examining Marston, Mack’s counsel noted that Marston would often interpret a particular word — say, “food”— as a coded reference to cocaine in one conversation only to ascribe an ordinary, innocent meaning to the very same word in another conversation. To illustrate these discrepancies, Mack’s counsel began to play recordings of conversations that Mar-ston had not identified as containing coded language, prompting the prosecution to challenge their relevance. Besides his initial objection to Marston’s qualifications as an expert in interpreting coded drug-related conversations, however, Mack’s counsel never objected to any of Marston’s specific interpretations.

The prosecution also called Detective Aaron David Penman to testify about the search of the Abingdon house and Mack’s arrest there.
