Explanation / Answer

31. a) probability of selecting a heart is 1/4, probability of selecting a club is also 1/4 so the probability of selecting a heart OR a club is
1/4 + 1/4 = 2/4 = 1/2.

b) probability of selecting a diamond is also 1/4 so the probability of selecting any of those is
1/4 + 1/4 + 1/4 = 3/4

c) probability of selecting heart is 1/4
probability of selecting a ace is 4/52 = 1/13

HOWEVER, we can take one of the ace away because it is the ace of hearts so the probability of selecting the ace of diamonds, spades or clubs is
1/52 + 1/52 + 1/52 = 3/52.

So the probability of selecting either of the above is:
3/52 + 1/4 = 3/52 + 13/52 = 16/52 = 8/26 = 4/13
