Question

Find the probability of drawing an Ace or a Spade from a well shuffled pack of $52$ playing cards

Answer 1

Solution:

Let $E$ be the event of drawing an ace or spade from a well shuffled pack $52$ playing card.

There are $13$ spades and $4$ aces but ace spade is already included in the $13$ spades so the number of cards$=13+3=16.$

Total number of cards$=52.$

$\therefore P\left(E\right)=\frac{16}{52}=\frac{4}{13}$
