Problem: operation # is defined as adding a randomly selected two digit multiple of 12 to a randomly selected two digit prime number and reducing the result by half . if operation # is repeated 10 times , what is the probability that it will yield at least two integers ?
Rationale: "any multiple of 12 is even . any two - digit prime number is odd . ( even + odd ) / 2 is not an integer . thus # does not yield an integer at all . therefore p = 0 . answer : a ."
annotated_formula: divide(add(12, add(10, const_3)), const_2)
