Answer 2

Answer:

(i) 1/2

(ii)1/26

(iii)1/13

(iv)1/4

Step-by-step explanation:

The total number of cards in a deck is 52, so while taking probability ,the number should be divided by the total which is 52.

1) There are 26 black cards , which are grouped as clubs and spades! So when divided by 52 ,it becomes 1/2.(on simplifying)

2) There are only 2 black kings , one from spades and other from clubs! So when divided by 52 ,it becomes 1/26.(on simplifying)

3) There are 4 aces in the whole deck, one from each group! So when divided by 52 , it becomes 1/13.(on simplifying)

4) Each group has 13 cards and so had diamonds also! So when divided by 52 , it becomes 1/4.(on simplifying)
