3.) Consider a standard 52-card deck of playing cards. If I randomly draw one card from this deck, what is the probability that:

c.) the card is a face card
d.) the card is a black heart
Solution
3.) Consider a standard 52-card deck of playing cards. If I randomly draw one card from this deck, what is the probability that:
a.) the card is red
There are 26 red cards out of 52 cards, so the
probability is P(R) = 26/52 = 1/2
b.) the card is a queen or a jack
There are 4 queen and 4 jack cards
probability is P(Q or J) = 8/52 = 2/13
c.) the card is a face card
There are 4 Jacks, 4 queens, and 4 kings which are face cards,
P(F) = 12/52 = 3/13
d.) the card is a black heart
There is one black heart
probability is P(black heart) = 1/52
