A simply supported concrete beam is loaded with a load P which can be represented by the following relationship P=5P1+3P2-Pg where P1. P, and Pg are statistically independent normal variables as shown in the Table below. Assuming the beam has been found to have a mean allowable load of 100 kN with a coefficient of variation (COV) of 0.1, determine the probability of failure of this beam. Mean (KN) Standard deviation (kN) P1 12 2 10 2 Pg 0.1 Select the correct answer from the drop-down lists below: What is the safety index? [ Select ] What is the probability of failure of this beam?
