Question

what is the probability that the card drawn from a stack of 52 cards is a face card or a black card?​

Answer 1

Answer: 8/13

Explanation:

There are 52 cards in a deck.

26 cards are black --> P(Black) = 26/52

Face cards are J, Q, K. There are 12 face cards --> P(Face) = 12/52

6 Face cards are black --> P(both) = 6/52

Face card or Black card - both Face card & Black

`(26)/(52)` +
`(12)/(52)` -
`(6)/(52)`
`=(32)/(52)`

`(32)/(52)/ (4)/(4)=(8)/(13)`
