Question

A card is drawn from a deck of playing cards. What is the probability of getting 1) a red card 2) a face card 3) cards with
even numbers.

Answer 1

Total number of cards in a deck = 52

Question (1):

Number of red cards = 26

P(red card) = 26/52 = 1/2

Question (2):

Number of face cards = 12

P(face card) = 12/52 = 3/13

Question (3):

Even numbers = 20

P(Even numbers) = 20/52 = 5/13

Answer 2

1. probablity of getting a red card is
$\frac{26}{52} = 0.5$
2. probablity of getting a face card is
$\frac{12}{52} = 0.230769231$

3. probablity of getting cards with even numbers is
$\frac{20}{52} = 0.384615385$
