Box P consists of five cards numbered 1, 2, 3, 4 and 5 respectively. Box Q consists of three cards numbered 1, 3 and 5 respectively. A card is drawn at random from box P and at the same time another card is drawn at random from box Q. Calculate the probability that the sum of the two numbers drawn is 7 or the product of the numbers is odd.
