The hours of time that is required to repair an engine is modeled as a Weibull random variable with parameters
α
= 2 and
β =
10.

a) What is the probability that the repair will take longer than 6 hours?

b) 4 hours have gone by, and the repair is still not done. As of now, at the 4-hour mark, what is the probability that the repair will take longer than 6 hours?
