Question 743525: 1 card is drawn from a 52 card deck what are the probabilities of getting:
A. clubs or red queen
B. not a face card
C not a face card or number Answer by Edwin McCravy(20060) (Show Source):
Here's a deck of 52 cards:
A♥ 2♥ 3♥ 4♥ 5♥ 6♥ 7♥ 8♥ 9♥ 10♥ J♥ Q♥ K♥
A♦ 2♦ 3♦ 4♦ 5♦ 6♦ 7♦ 8♦ 9♦ 10♦ J♦ Q♦ K♦
A♠ 2♠ 3♠ 4♠ 5♠ 6♠ 7♠ 8♠ 9♠ 10♠ J♠ Q♠ K♠
A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣ J♣ Q♣ K♣
The probability of getting a club or a red queen is the probability of
getting any one of these 15 cards:
Q♥
Q♦
A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣ J♣ Q♣ K♣
So the desired probability is 15 out of the 52 or
--------------------------------------------------------------
The probability of getting a card that is not a face card is the probability of
getting any one of these 40 cards:
A♥ 2♥ 3♥ 4♥ 5♥ 6♥ 7♥ 8♥ 9♥ 10♥
A♦ 2♦ 3♦ 4♦ 5♦ 6♦ 7♦ 8♦ 9♦ 10♦
A♠ 2♠ 3♠ 4♠ 5♠ 6♠ 7♠ 8♠ 9♠ 10♠
A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣
So the desired probability is 40 out of the 52 or which
reduces to
--------------------------------------------------------------
The probability of getting a card that is neither a face card nor a number
is the probability of getting any one of these 4 aces:
A♥
A♦
A♠
A♣
So the desired probability is 4 out of the 52 or which
reduces to
