A card is selected from a deck of 52 playing cards. Find the probability of selecting
A) a seven given the card is not a face card (An ace is not a face card)
Since ALL "seven" cards are NOT face cards, probability is
4/52 = 0.077 = 7.7%
.
B) a spade given the card is red
Since ANY spade is not red:
13/52 = 0.25 = 25%
