# Find the probability.

Question asked by: mrpulley

Asked on: 01 Feb 2011

So there are 13 marbles in the hat. And you pick two. The chance the first is navy is therefore 3/13 and then it is not returned so on the second the chance is out of 12 so therefore that the second being not green is then 10/12

Multiply them together to get the chance of the combined probability to get 0.192
