Answer :

Total number of outcomes = Total number of cards = 49

1. An odd number

\text{No. of odd numbers from 1 to 49 = }\frac{(49 + 1)}{2}=25

Number of favorable outcomes = 25

Probability = }\frac{25}{49}

2. a multiple of 5

Favorable outcomes : 5, 10, 15, 20, 25, 30, 35, 40, 45

No. of favorable outcomes = 9

Probability = }\frac{9}{49}

3. a perfect square

Favorable outcomes :  1, 4, 9, 16, 25, 36, 49

No. of favorable outcomes = 7

Probability = }\frac{7}{49}=\frac{1}{7}

4. an even prime number

Favorable outcomes : 2

No. of favorable outcomes = 1

Probability = }\frac{1}{49}
