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:
[tex]P(\text{exactly 2) =}\frac{frequency\text{ at 2}}{\text{total frequency}}[/tex]
Where:
Total frequency = 12 + 20 + 38 + 20 + 10 = 100
Frequency at 2 = 20
Hnece, we have:
[tex]P(\text{exactly 2) = }\frac{20}{100}=0.2[/tex]
Thereforem the probability that a teenager has exactly 2 pairs of shoes in their closet is 0.2
