What is the probability of a face card given that the card is black?

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

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

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
