Question

A bag has four green marbles, three red marbles, and three yellow marbles. What is the probability that you pick a green marble, do not replace it, and pick a yellow marble?

Answer 1

add total marbles: 4+3+3 = 10 marbles

there are 4 green so probability of picking green is 4/10 can reduce to 2/5

after taking one marble out there is a total of 9 left and there are 3 yellow so probability would be 3/9 can reduce to 1/3
