Explanation / Answer

We know that

Probability of a event = number of favourable outcomes /total number of out comes.

Given

The total number of cards 52

Hance if we select one card we have 52 options. It means that the total number of out comes are 52.

a) Probability that card is Club

We know that total number of Club in 52 card are 13

Hance total number of favourable outcomes are 13

So the probability that card is Club =13/52=1/4=0.25

b) Probability that card is Red

TOTAL Number of red cards are 26 (13+13)

That is total number of favourable outcomes are 26

HanceProbability of getting red = 26/52=1/5=0.5

C) NOT A Heart

That is card may be Spade / Club or Diamond

So the total number of favourable outcomes are 39 (13+13+13)

Hance

Probability card is not Heart =39/52=3/4=0.75

Answers

a) 0.25

b) 0.50

c) 0.75
