2 A safety net can stand the fall of the total of 2700 pound

2. A safety net can stand the fall of the total of 2700 pounds of objects from a construct ion site. Say 12 random objects are falling down into the act at the same time, and the weight of each of them is (225. 625). What is the probability that the net withstands the impact?

Solution

z = (2700/12 - 225) / (25/sqr(12)) = 0

Therefore , from z table ,

P = 0.5 Answer
