Answer 2

P(sophomore & volleyball) = 0.26

Explanation:

We have to find the probability that a randomly chosen person from this group is a Sophomore and attended the volleyball game

Probability that a person selected is a Sophomore:

Total persons: 137

Number of sophomores: 77

Probability = Desired outcome / Total possible outcomes

P(sophomore) =
`(77)/(137)`

Now finding Probability that a person selected has attended the volleyball game:

Total persons: 137

Number of persons who attended volleyball: 77

P(volleyball) =
`(66)/(137)`

Probability that a person is sophomore and attended volleyball:

P(sophomore & volleyball) =
`(77)/(137) * (66)/(137)`

= 0.26
