Question

The king, queen and jack are removed from a deck of 52 playing cards and then shuffled. One card is selected from the remaining cards. Find the probability of getting an ace.

Answer 1

Once the royalty cards are removed, we have 10 in each suit. So, we’ll have a total of 40 cards, of which 4 are aces.
Hence, the required probability is $\frac{4}{40}$ = $\frac{1}{10}$
