    61.5%

    Step-by-step explanation:

    Let's find all the demographics first:

    Sophomores in the class (total 15):

    Female: 5

    Male : 10

    Freshmen in the class (total 11):

    Female: 3

    Male: 8

    There are 11 freshmen (male and female) and 5 female sophomores. Thus, the probability of choosing one of these 16 people in a class of 26 is 16/26 or 61.5%.
