Question

Find the probability that a teenager has exactly 2 pairs of shoes in their closet

Answer 1

Given the table:

Shoes 1 2 3 4 5

Frequency 12 20 38 20 10

Let's find the probability that a teenager has exactly 2 pairs of shoes.

To find the probability, apply the formula:

`P(\text{exactly 2) =}\frac{frequency\text{ at 2}}{\text{total frequency}}`

Where:

Total frequency = 12 + 20 + 38 + 20 + 10 = 100

Frequency at 2 = 20

Hnece, we have:

`P(\text{exactly 2) = }(20)/(100)=0.2`

Thereforem the probability that a teenager has exactly 2 pairs of shoes in their closet is 0.2
