A concrete footing, exerting an applied preure of 200 kPa on the oil, may fail from
bearing capacity (B) or exceive ettlement (S). Due to oil variation, the following
are given:
Bearing capacity i normally ditributed with mean 500 kPa and tandard deviation= 200 kPa. Settlement i log-normally ditributed with mean=1. 5 cm and tandard deviation =0. 3 cm. The probability that the footing fail in bearing capacity knowing that it
had ettled exceively i 0. 2. Maximum permiible ettlement i 2. 5 cm. (i. E. S> 2. 5 cm i conidered
exceive ettlement). Calculate the probability that the footing will fail
