m = { - 6 , - 5 , - 4 , - 3 , - 2 } t = { - 3 , - 2 , - 1 , 0 , 1 , 2 , 3 , 4 , 5 } if an integer is to be randomly selected from set m above and an integer is to be randomly selected from set t above , what is the probability that the product of the two integers will be negative ?
we will have a negative product only if 1 , 2 , 3 , 4 , or 5 are selected from set t . p ( negative product ) = 5 / 9 the answer is e .
divide(5, add(4, 5))
