Answer:
a) 1/2 = 50%
b) 3/4 = 75%
c) 1 / 52 or 1,9%
Step-by-step explanation:
In a standard deck of cards, there are 52 cards in total:
13 are hearts, 13 are diamonds, 13 are clubs and 13 are spades.
(a) Compute the probability of randomly selecting a club or spade
How many cards are a club or a spade?
C = 13 clubs + 13 spades = 26 cards
Out of the 52 total, that means that:
P (club or spade) = 26/52 = 1/2 = 50%
(b) Compute the probability of randomly selecting a club or spade or heart.
How many cards are a club or a spade?
C = 13 clubs + 13 spades + 13 hearts = 39 cards
Out of the 52 total, that means that:
P (club or spade or heart) = 39/52 = 3/4 = 75%
(c) Compute the probability of randomly selecting a two or diamond.
There's only ONE two of diamond in regular deck of cards, so...
P(2 of diamond) = 1 / 52 or 1,9%
