SOlution:-
2)
a) The probability of getting a club is 0.25.
Number of clubs = 13
Total number of cards = 52
The probability of getting a club = 13/52 = 0.25
b) The probability of getting a facecard or a heart is 0.4231.
Number of facecards or heart = 13 + 12 - 3 = 22
Total number of cards = 52
The probability of getting a facecard or a heart = 22/52 = 0.4231
c) The probability of getting a 6 and a spade is 0.01923.
Number of 6 and a spade = 1
Total number of cards = 52
The probability of getting a 6 and a spade = 1/52 = 0.01923
d) The probability of getting a king is 0.07692.
Number of kings = 4
Total number of cards = 52
The probability of getting a king = 4/52 = 0.07692
e) The probability of getting a red card is 0.50.
Number of red cards = 26
Total number of cards = 52
The probability of getting a red card = 26/52 = 0.50
