Question

The probability that both the numbers come up are prime numbers

(a) 1/2

(b) 2/3

(c) 3/4

(d) 1/4​

Answer 1

Answer:

The number of favourable outcomes is the sum of occurrences of all the favourable outcomes. So, the number of favourable outcomes =1+2+4+6+2=15. We know that the number of possible outcomes is 36. Thus, the probability of getting the sum of two numbers as prime numbers is =1536=512.
