23. Since there is a king that is also a club, A and B are not mutually exclusive.
The correct answer is B)
24. A student taking maths course may also be a business major.
Therefore, the events are not mutally exclusive.
The correct answer is B)
25. There are 4 aces and 12 other hearts out of a total of 52 cards.
Probability = 16 / 52 = 4/13 which is given in C)
26. P(A or B) = 1/4
P(A) = 1/7 P(A and B) = 1/9
P(B) = P(A or B) + P(A and B) - P(A)
= 1/4 + 1/9 - 1/7
= 63/252 + 28/252 - 36/252
= 55/252
