Step-by-step explanation:

Hello :)

By adding up the number of students which we will call a sample size, then dividing it by each individual categorization students picked, we can then figure out the percentage of people who chose that categorization.

18+24+24+54=120

Let's find every percentage.

Popcorn: 18 students choose this choice. Divide that by the total of students to get 0.15, then multiply by 100 to get 15%.

Pretzels: 24 students chose this. Divide by the total to get 0.2, multiply by 100 to get 20%.

Chips: 24 students chose this. Divide by the total to get 0.2, multiply by 100 to get 20%.

Candy: 54 students chose for candy. Divide this by the total amount of students to get 0.45, multiply by 100 to get 45%.

The correct percentage graph is D. Popcorn clearly says that it is 15 percent, and every other section is the correct amount of percentage.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
