## Homework Statement

"The compressive strength of a concrete specimen follows a normal distribution with a mean value of 2.8 ksi and a coefficient of variation (COV) of 0.1. If the applied stress is 2.5 ksi, find the probability of failure."

## Homework Equations

normal distribution formula

## The Attempt at a Solution

I got the variance to be .28 ksi but i don't know how to find the probability of failure without knowing the maximum failure stress of the specimen. Can anyone help me out?
