Here is the explanation.

The given numbers are 1, 2, 3, ...., 12.

(a) The Prime numbers are 2, 3, 5, 7, 11.

     Here, number of prime numbers = 5

     Probability of getting a prime number

(b) Here, even prime number is 2 (only)

∴ Probability of getting an even prime number

(c) Here, even numbers are 2, 4, 6, 8, 10, 12 

     Number of even numbers = 6

    ∴ Probability of getting an even number
