out of a deck of 52 playing cards, two black kings and 4 red cards( not king) are removed. A card is drawn at random. Find the probability that the card drawn is :
(a) a black jack
(b) a black queen
(c) a black card
(d) a king

Answer :

We know that 4 red cards and 2 black king are removed. Therefore, no. of cards left in the deck = 52 - 6 = 46
 
a) No. of black jacks in a deck = 2
Total number of cards = 46 
Probability = 2/46 = 1/23

b) No. of black queens in a deck = 2 
Total number of cards = 46 
Probability = 2/46 = 1/23

c) No. of black cards = 13 - 2 = 11 (As two black kings have been removed)
Total number of cards = 46 
Probability = 11/46

d) No. of kings = 4 - 2 = 2 (As two black kings have been removed)
Total number of cards = 46 
Probability = 2/46 = 1/23

Hope that helps !!

Probability = total number of times event occurs/ total number of events.

a) 2/ 46 = 1/23

b) 2/46 = 1/23

c) 24/ 46 = 12/23

d) 2/ 46 = 1/23.
