Question

There are five blue crayons, seven yellow crayons, and eight red crayons in a box. If one is randomly drawn and replaced 15 times, find the probability of drawing exactly four blue crayons.

Answer 1

0.225

Explanation:

5 + 7 + 8 = 20 crayons.

we want 4 blue crayons from 15 draws. p(blue) = 5/20.

p(4 from 15 draws) = 0.225
