... four and eight (inclusive) or is a club
Answers (1)
A deck of 52 cards
Find the probability that the card is between four and eight (inclusive) or is a club.
between four and eight (inclusive): (♦,♣,♠,♥) * (4, 5, 6, 7, 8) = 4 * 5 = 20
or is a club: (♣) * 13 = 1 * 13 = 13
In order to not count the (♣) (4, 5, 6, 7, 8) twice,
we have to subtract 5 from the sum 20 + 13 = 33:
Allowed picks:33 - 5 = 28.
The probability to randomly pick one of these 28 cards from the deck is then:
P = 28 / 52 = 4 / 13 ≈ 0.538 or 53.8%.
It's, of course:
P = 28 / 52 = 7 / 13 ≈ 0.538 or 53.8%.
It's, of course:
P = 28 / 52 = 7 / 13 ≈ 0.538 or 53.8%.
