Answer:
p(prime) = 5/12
Explanation:
The possible totals from rolling two dice are between 2 and 12, inclusive. The primes in that range are ...
2, 3, 5, 7, 11
Probability
We assume that "fair dice" means the probability of any outcome is the same as any other. The attached table shows (shaded) all of the 36 possible outcomes that result in a prime number total. There are 15 of them.
The probability of getting a prime total is 15/36 = 5/12.
P(prime) = 5/12
