Question

What is the probability of selecting 4 cards from a deck of 52 cards if all the cards are of same colour???

Answer 1

Total no. of cards= 52

Case 1

Let the card be chosen are of red colour

total no. of outcomes =4

P( red colour) = 4/52

=1/13

Case 2

Let the card be chosen is from black card

Total no. of outcomes =4

P( black cards) = 4/52

=1/13
