p = [?]

Answer 1

The question provides a table of the number of pairs of shoes students have in their closet.

According to the table,

12 students have 1 pair of shoes in the closet

20 students have 2 pairs of shoes in the closet

38 students have 3 pairs of shoes in the closet

20 students have 4 pairs of shoes in the closet

10 students have 5 pairs of shoes in the closet.

This means that for this survey, the total number of students in consideration is:

$12+20+38+20+10=100\text{ students}$

The question then asks us to find the probability that a teenager has 2 pairs of shoes.

There are only 20
