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.

A.

0.21

B.

0.22

C.

0.30

D.

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
