"which of the following is an example of a prejudice? a. giving african americans higher mortgage interest rates b. only searching people of certain ethnicities at the airport c. making fun of classmates for looking different d. believing that asians are better at math e. not hiring someone because of their ethnicity"

d) Believing that Asians are better at math

Explanation: Prejudice is defined as feeling that tends to be negative towards other people or thing .It is an unjust opinion that someone forms usually on basis of race, ethics, etc. It is usually based on non-personal experience and is conceived from some other source
