A card is drawn at random from a standard deck of cards. Find the probability of getting the following (assume the drawn card is put back into the deck after each draw):
a. Black card
1
2
b. Heart card
1
4
c. King card
1
13
a. There are 26 black cards in a standard deck of 52 cards. So the probability of drawing a black card is 26/52 = 1/2.
b. There are 13 heart cards in a standard deck of 52 cards. So the probability of drawing a heart card is 13/52 = 1/4.
c. There are 4 king cards in a standard deck of 52 cards. So the probability of drawing a king card is 4/52 = 1/13.
