3/5

11/20

1/20

Answer 1

The answer is B. 11/20

Answer 2

Answer:

Option A is correct.

Step-by-step explanation:

Total Number of Outcome = 100

Number of even numbers = 50

Number of perfect square = 10

$Probability=\frac{Number\:of\:favorable\:outcome}{Number\:of\:total\:outcome}$

$Probability=\frac{50}{100}+\frac{10}{100}=\frac{60}{100}=\frac{3}{5}$

Therefore, Option A is correct.
