when two dice are rolled , what is the probability that the sum is either 7 or 11 ?
total number of outcomes possible = 36 probability of getting sum of 7 = 6 / 36 probability of getting sum of 11 = 2 / 36 probability that the sum is either 7 or 11 = 6 / 36 + 2 / 36 = 2 / 9 answer : e
divide(add(7, const_1), multiply(const_6, const_6))
