Question

A card is drawn from a​ well-shuffled deck of 52 cards. Find the probability of drawing a diamond or a spade.

Answer 1

2/13

Explanation:

For a deck of card

Total cards = 52

Total spade = 4

Total diamond = 4

pr(drawing a spade) = number of spade/total cards

pr(drawing a spade) = 4/52 = 1/13

pr(drawing a diamond) = 4/52 = 1/13

Pr(diamond or a spade) = 1/13 + 1/13 = 2/13
