There are 5 green marbles, 4 red marbles, 3 blue marbles and 3 yellow marbles in a bag. Bryan select's a marble at random. Determine the probability that two green marbles are chosen. And here are your answer choice you have A.2/21, B.4/45, C.2/15, D.1/3

1/3

Step-by-step explanation:

(5 + 4 + 3 + 3) x 2 = 30

Multiplied by two because two marbles are being picked.

10/30 = 1/3

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
