There are 7 black marbles and 9 white marbles in a bag. what is the probability of drawing 2 black marbles then a white marble without replacement

The probability of drawing to marbles then a white one without replacement will be as follows;

total number of marbles=16

total number of black marbles=7

total number of white marbles=9

probability of drawing a black marble on first=7/16

probability of drawing a black marble on second draw=6/15

probability of drawing a white marble on the 3rd draw=9/14

thus the P (B and B and W)

=7/16*6/15*9/14

=9/80

the answer is 9/80
