From a pack of 52 cards, two cards are drawn together at random. What is the probability of both the cards being kings? Choices
A) 1/15  B) 25/57  C) 35/256  D) 1/221  E) 2/15
Let S be the sample space.   Then, n(S) = 52C2 =	(52 x 51)/(2x1)	= 1326.   Let E = event of getting 2 kings out of 4.   n(E) = 4C2 =	(4 x 3)/(2x1)= 6.   P(E) =	n(E)/n(S)	=	6/1326=1/221	.   Option 1/221
