A box contains 14 white balls and 6 black balls. Find the probability of first drawing a black ball and then a white ball without replacement.
0.21
0.22
0.30
0.70
Correct answer is B
The probability of picking a black ball = 66+14=620
Probability of a white ball without replacement = 1419
Probability of a black ball and then white without replacement = 620×1419=2195=0.22
