Question

Sarah has a bag of 100 marbles. 40 are blue, 40 are green, and 20 are purple.

What is the probability of Sarah picking a blue marble on 2 consecutive draws without replacement?

Answer 1

Answer: The probability of Sarah picking a blue marble on 2 consecutive draws without replacement = 15.8%

Explanation:

Given: Sarah has a bag of 100 marbles. 40 are blue, 40 are green, and 20 are purple.

The probability of Sarah picking a blue marble on 2 consecutive draws without replacement =
`(40)/(100)*(39)/(99)=0.157575757576\approx15.8\%`

Hence, the probability of Sarah picking a blue marble on 2 consecutive draws without replacement = 15.8%
