Question

Molly has a jar containing 4 yellow, 3 blue, 3 green, and 2 orange marbles
If Molly removes one marble without looking, records the color, and places the marble back in the jar before drawing again, what is the probability that she will remove two yellow marbles?

Answer 1

Answer: .111 with a bar notation over the last 1 or 11.1%

Step-by-step explanation:

There are 12 marbles in total. There are 4 yellow marbles. Therefore there is a 4/12 probability of Randomly picking a Yellow marble the first time . Since she placed the marble back, there is a 4/12 probability of getting a yellow marble the 2nd time.

(4/12)(4/12) = 16/144 = 1/9 = .111 with a bar notation over the last 1 or 11.1% (about 11%)
