A restaurant has 89 yellow dishes and 11 white dishes. If I go there with my wife, and we ordered one service each one, what is the probability that both dishes will be white? Pick one
A) 1/100
B) 2/100
C) 1/90
D) 2/90
E) 1/89
There are 11 white dishes in a group of 89 + 11 that is 100 dishes. Thus the probability of taking 2 white dishes is: (11/100)(10/99) = 1/90. The correct answer is 1/90.
