Question

From the deck of 52 cards a card is chosen at random what is the probability that it is a club card or a king

Answer 1

In a deck of 52 cards, we have in total 12 clubs and in total 4 kings, of which one belongs to club.

So, P(Club or King) = 12 + 4 - 1 / 52

...because one king is common in 12 club cards.......

=> P(club or king) = 15/52
