Question

Two cards are drawn from a standard deck of cards. What is theprobability that both cards are either Ace's or odd numbered cards?

Answer 1

Total cards = 52

Aces = 4

Odd numbers = 16

First drawing:

$AO_1=\frac{16}{52}+\frac{4}{52}=\frac{20}{52}$

Second drawing

$AO_2=\frac{19}{51}$

The total probability is

$T=\frac{20}{52}\cdot\frac{19}{51}=\frac{95}{663}$
