A box contains 14 pairs of shoes (28shoes in total). If two shoes are selected at random, what it is the probability that they are matching shoes?
Select the correct option:
A) 1/190 B) 1/20 C) 1/19 D) 1/27 E) 1/9
The problem with your solution is that we don't choose 1 shoe from 28 but rather choose the needed one AFTER we just took one and need the second to be the pair of it. So, the probability would simply be: 1/1*1/27(as after taking one at random there are 27 shoes left and only one is the pair of the first one)=1/27   Answer: 1/27
