A standard deck of cards contains 52 cards. One card is selected from the deck.
|
(a) |
Compute the probability of randomly selecting
a five or king. |
|
(b) |
Compute the probability of randomly selecting
a five or king or queen. |
|
(c) |
Compute the probability of randomly selecting
a seven or club. |
(Type an integer or a decimal rounded to three decimal places as needed.
total number of cards = n = 52
(A) there are 4 five cards in each suit and 4 king cards in each suit
So, favorable outcome = 8
total outcome = 52
Probability = favorable/total
= 8/52
= 0.154
(B)
there are 4 five cards in each suit and 4 king and 4 queen cards in each suit
So, favorable outcome = 4+4+4 =12
total outcome = 52
Probability = favorable/total
= 12/52
= 0.231
(C)
there are 13 club cards and 3 seven cards in each suit (excluding 7 of club)
So, favorable outcome = 13+7 =20
total outcome = 52
Probability = favorable/total
= 20/52
= 0.385
