A standard deck of cards contains 52 cards. One card is selected from the deck.
a) Compute the probability of randomly selecting a 9 or 10
b) Compute the probability of randomly selecting a 9 or 7 or 2
c) Compute the probability of randomly selecting a 3 or diamond.

Answer 1

Ans:

a) the probability of randomly selecting a 9 or 10

total number of cards which is 9 or 10 =4+4=8

probability of randomly selecting a 9 or 10= 8/52

b) the probability of randomly selecting a 9 or 7 or 2

total number of cards which is 9 or 7 or 2=4+4+4=12

probability of randomly selecting a 9 or 7 or 2=12/52

c) the probability of randomly selecting a 3 or diamond.

total number of cards which is 3 or diamond =13+3*1=16

probability of randomly selecting a 3 or diamond=16/52
