How do i do this problem explain. : )

Divide 24 by 30 because 24 OUT OF 30 students are wearing a shirt. You will get the probability of %80 so subtract that out of %100 and you will get C, .20 or %20

When you divide the twenty four students, wearing white shirts, out of thirty students you get 0.8 out of the calculator.

MY best guess is letter choice E.

(please don't be mad at me if it isn't correct, I'm just guessing here T-T)

Xis equal to three

These are the multiples of 15 but what you are probably asking or what are the factors of 15
