Question

A bag contains 7 red marbles, 5 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be red?

Answer 1

8.374%

Explanation:

the chance of drawing one red marble is 7/16

then you multiply that by 7/16 two times

basically

(7/16)^3 = 0.0837402344

because that is a percent you would turn it into

8.37402344

then you would round it to

8.374
