Question

You have a hat containing 8 red chips, 4 green chips, 5 yellow chips, and 3 white chips. Find the following probabilities and write the answers as simplified fractions:

(4 points each)

Probability of picking a red chip?

Probability of not picking a green chip?

Probability of picking one chip and it is a yellow or green chip?

Answer 1

Explanation:

There are 20 chips in total.

P(red) = 8/20 = 2/5

P(not green) = 16/20 = 4/5

P(yellow or green) = 9/20
