Question

A glass jar contains 1 red, 3 green, 2 blue, and 4 yellow marbles. If you were to pull one marble out after the other, what would be the probability of getting a yellow and then a green marble? Group of answer choices 12% 13% 14% 15%

Answer 1

I believe it's 13%

Explanation:

There is 10 total marbles

So the P(Yellow AND Green)

Yellow = 4/10

Green = 3/9 (because we had already chosen 1 yellow so now instead of 10 marbles there is 9 left)

Because it says the word 'AND' that means multiply these two fractions which = 2/15 which is 13.3% so I would choose 13%

This is assuming we dont put the yellow marble back first to grab the next marble
