If two numbers are randomly taken out in the interval (0, 1), the probability that the sum of the two numbers is less than 56 is zero______ .

If two numbers are randomly taken out in the interval (0, 1), the probability that the sum of the two numbers is less than 56 is zero______ .

As shown in the figure, when the sum of two numbers is less than 56, the corresponding point falls on the shadow, ∵ s shadow = 12 (56) 2 = 2572, so take two numbers randomly in the interval (0, 1), then the probability that the sum of two numbers is less than 56 is p = 2572
