PROBABILITY 8


A certain man takes 2 cards from a standard deck of 52 cards.
What will be the probability of getting a pair of spades?

Solution

(This is a problem with replacement)

n(E) = 13, n(S) = 52

P(E) = n(E)
            n(S)

1st pick = 13/52
2nd pick = 13/52 as well.


P(2 spades) =   13      x    13
                        52            52

P(2 spades) =    169    =      1 
                        2704          16  


Therefore Probability of drawing 2 spade cards is 1/16
