Question

Select two type cards from the pack of 52 cards. What is the probability of selecting red king or black queen?

Answer 1

Since there are two red kings and two black queens out $52$ cards.

$P\left(Redking\right)=\frac{2}{52}$

$P\left(BlackQueen\right)=\frac{2}{52}$

As both the events are mutually exclusive,

Therefore,

$P\left(Redkingorblackqueen\right)=\frac{2}{52}+\frac{2}{52}=\frac{1}{13}$
