Question

a bag contains 6 blue marbles, 10 red marbles, and 9 green marbles if two marbles are drawn at random without replacement what is the probability that two green marbles are drawn

Answer 1

P ( first one drawn is green) = 9 /25

P(second drawn is green)  = 8/24 = 1/3

Probabilty both green  = 9/25 * 1/3 = 9/75  =  3/25 answer
