Question

If two dice are rolled, What is the probability that

(i) the sum of the numbers on the dice is a prime number?

(ii) the sum of the numbers on the dice is 8?​

Answer 1

Answer:

Then, the probability that the sum of numbers appearing on them is a prime number, is 1) 5/12 2) 7/18 3) 13/36 4) 11/36. When two dice are thrown, the total number of sample spaces is 36. Hence, the probability of getting a sum of prime numbers = 15/36 = 5/12.

Answer 2

Answer:

i) probability = 2 ( 1+2 , 2+3 )

ii) probability = 0 ( because the dice do not have a digit 8 )
