Answer:
P(face | Black) = 3/13
Step-by-step explanation:
total number of cards in standard deck of cards = 52
Total number of face cards = 12
Then P(face cards) = 12/52
Total number of black cards = 26
Then P(black cards) = 26/52
Total number of cards that are both black and face cards = 6
Then P(black and face cards) = 6/52
Then conditional probability of getting face card given that the card is black is given by:
P(face | Black) = P( face & Black) / P(Black)
P(face | Black) = (6/52) / (26/52)
P(face | Black) = 6/26
P(face | Black) = 3/13
Answer:
The probability of a face card given that the card is black = 3/26
Step-by-step explanation:
Points to remember
There are total 52 cards. It is divided into 4 suites, 13 each.
Spades, Clubs, Hearts and Diamonds
Spades and Clubs are black.
Hearts and Diamonds are red
In each suites there are 3 face cards.
To find the probability
There are total 52 cards. And 6 black face cards
The probability of a face card given that the card is black =6/52
= 3/26
