A certain man takes 2
cards from a standard deck of 52 cards.
What will be the
probability of getting a pair of jacks?
Solution
(this is a problem with
replacement)
n(E) = 4, n(S) = 52
P(E) = n(E)
n(S)
1st pick = 4/52
2nd pick = 4/52 as well.
P(Jacks) = 4 x 4
52 52
P(Jacks) = 16
= 1
2704 169
Therefore Probability of drawing 2 jacks
is 1/169
