**Damon**, Wednesday, May 23, 2012 at 7:14pm5 of C = 1/52

5 = 4/52 =1/13

club = 1/4 = 13/52

jack = 4/52 =1/13

spade same as club

J of S, same as 5 of C

You only took one card. It can not be 5 and jack

five or jack 1/13 + 1/13 = 2/13

heart and jack is jack of hearts 1/52

Heart OR jack

draw Venn diagram

There are 13 hearts

There are 4 jacks, three of which are not hearts. The jack of hearts is the intersection of the sets, careful not to count it twice.

So out of the 52 cards

13 are Hearts and 3 more are jacks that are not hearts

total = 13+3 = 16

so

16/52 = 4/13

heart or jack = 1/4 + 3/52
