Question

Michael has a drawer with 8 pairs of black socks and 12 pairs of white socks. Without looking he takes a white pair of socks out of the drawer. What is the probability that the next pair he takes out is black?
A) 11/19
B) 11/20
C) 8/11
D) 8/19

Answer 1

D) 8/19

Before it was 8/20, but now there are still 8 black pairs, but only 19 pairs in total.

Answer 2

The Probability that the next pair Michael takes out is black = $\frac{8}{19}$

What is Probability?

Probability is deals with "occurrence of Random event. The value is expressed from 0 to 1".

According to the question,

Total number of pairs of socks = 8 + 12 =20

Probability of taking pairs of black socks,  P(B)=$\frac{8}{20}$

Probability of taking pairs of white socks,  P(W)=$\frac{12}{20}$

But after taking Black pair socks the total number socks =19.

Hence, the Probability of taking Black pair socks from drawer is $\frac{8}{19}$.
