Question

A jar of gumballs contains 10 blue gumballs, 20 green gumballs, 15 yellow gumballs, and 25 pink gumballs. You reach into the jar and randomly select a gumball, then select another while replacing the first gumball back. What is the probability that you draw a green gumball as a percent and a fraction in simplest form?

Answer 1

There are 20 greens in 70 gumballs

The chance of drawing <u>zero</u> green ones is 50/70 * 49/69
