Problem: let a be the event that a randomly selected two digit number is divisible by 2 and let b be the event that a randomly selected two digit number is divisible by 5 . what is p ( a and b ) ?
Rationale: "p ( a and b ) = 1 / 2 * 1 / 5 = 1 / 10 the answer is b ."
annotated_formula: multiply(divide(subtract(2, const_1), multiply(subtract(2, const_1), 2)), divide(multiply(subtract(2, const_1), const_2), multiply(subtract(2, const_1), 2)))
