उत्तर
The cards are numbered from 1 to 49.
∴ Total number of outcomes = 49
An even prime number is 2.
So, the favourable number of outcomes is 1.
∴ P(number on the drawn card is an even prime number) =\[\frac{\text{ Favourable number of outcomes }}{\text{ Total number of outcomes }} = \frac{1}{49}\]
