Question 1043226: a bag contains six marbles:two red,one yellow, and three blue. what is the probability of randomly selecting two red marbles in a row, assuming the marbles are not put back in the bag after being drawn? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there,
Red 2
Yellow 1
Blue 3
Total = 6
Probability of drawing red
first time = 2/6 = 1/3
Probability of drawing a second red
if first red not replaced = 1/5
Applying rule:
P(A and B) = P(A) x P(B)
Given A has occurred)
1/3 x 1/5 = 1/15
Hope this helps
:-)
