Question

When 2 cards are drawn from a well-shuffled pack of playing cards. what is the probability that they are of the same suit?

Answer 1

For selecting the first card there is no condition
So it can be from any of the suit
After taking it out 51 cards will be left with 12 cards of the same suit of the first one and 13 cards of the rest of the suit
So for selecting the second card (from same suit as the first) the favorable outcomes are 12 and the sample set is 51
So the probability is 12/51=4/17..

Answer 2

Answer:

it is 4c1 × 13c2/ 52c2

this is because we have to select one soot from 4 soots
