Question

You randomly pull a rock from a bag of rocks. The bag has 2 pink rocks, 4 green rocks, 5 speckled rocks, and 5 black rocks.

Answer 1

• 11/16
• 1/8

Explanation:

Total number of rocks:

• 2 + 4 + 5 + 5 =16

Probability of not black:

• P(not black) = number of not black/total number
• P(not black) = (2+4+5)/16 = 11/16

Probability of pink:

• P(pink) = number of pink/total number
• P(pink) = 2/16 = 1/8
