In a Calculus class, there are 11 freshman and 15 sophomores; 5 of the sophomores are females,

and 8 of the freshman are males. If a student is selected at random, what is the probability of

selecting a freshman or a female? P (Freshman or Female) =

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%.
