a)
b) 1 / 1
d)

Answer 1

`(7)/(31) = 0.2258 = 22.58\%` probability that a randomly selected student prefers hip hop music.

Explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

14 students prefer hip hop music

There are 18 + 8 + 20 + 14 = 62 students

So

`p = (14)/(62) = (7)/(31)`

`(7)/(31) = 0.2258 = 22.58\%` probability that a randomly selected student prefers hip hop music.
