Answers:

Work Shown:

26)

1/2 = probability of an odd number, since half of the numbers are odd

1/2 = probability of tails

(1/2)*(1/2) = 1/4 is the probability of both events happening at the same time

27)

13/52 = probability of pulling out one club

12/51 = probability of pulling out a second club, assuming the first one is not put back

(13/52)*(12/51) = 156/2652 = 1/17 = 0.0588 is the probability of pulling two clubs in a row (without replacement).

28)

11/27 = probability first person has blonde hair

10/26 = probability second person has blonde hair (cannot reselect the first person again)

(11/27)*(10/26) = 110/702 = 55/351 = 0.157 is the probability of selecting two people with blonde hair
