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