Best answer

1. a) 1/26 

Total number of cards = 52 

Total number of kings of red colour = 2

2. d) 3/13

Total number of cards = 52

Face cards are King, Queen and Jack

Each type has 4 cards

Total number of face cards = 3 x 4 = 12

3. b) 1/52 

Total number of cards = 52

we have 4 jack cards

 P(getting a jack of hearts) = Number of jack of hearts cards / Total number of cards

= 1/52

4. a) 3/26

Total number of cards = 52

Face cards are king, Queen and jack

Total number Red face cards = 6

5. d) 1/4

Total number of cards = 52

We have 4 suits -

Spade, Club, Diamond and Hearts

Total number of spade cards = 13
