Question

From a pack of well shuffled deck of $52$ playing cards, all the even primes are removed. A card is then drawn at random. Find the probability that it is a prime number.

Answer 1

Probability :

prime numbers are 2,3,5,7

$\therefore P=\frac{4\times 4}{52-4}=\frac{16}{48}=\frac{4}{12}=\frac{1}{3}$
