(B) 23/49

(C) 13/26

(D) 23/52

Answer 1

The correct option is: (B) 23/49

Explanation:

No. of cards left = 52 - 3 = 49 

No. of cards of spade left = 13 - 3 = 10 

No. of black cards left = 13 + 10 = 23 

['.' Spade is of black colour] 

Total no. of ways to draw a card = 49 

No. of ways to draw a black card = 23 

.'. Required probability = 23/49
