Question

The numbers 2, 3, 4, and 5 are indicated on cards that are placed in a hat.

Answer 1

1.  This probability is 1/2*1/2=1/4, or 0.25.
2.  There are three ways to do this: draw two 2s, a three then a two, or a two then a three.  So our probability is 3/16=.1875.
3.  We already calculated the probability that the sum is less than 6.  Using similar methods, we calculate that there are three ways for a sum to be greater than 8, so our probability is 6/16=0.375.
