Determine the probability that a random sample of yarn

The breaking strength of the certain kind of yarn produced by the vendor has normal distribution with mean 95 and standard deviation 11.

a. Determine the probability that a random sample of yarn has a breaking strength that is within 1.5 standard deviations of the mean?

b. Suppose five samples of yarn are selected randomly. What is the probability that at least one of them has a breaking strength of at least 100?
