Based on extensive testing, it is determined by the manufacturer of a washing machine that the time Y (in years) before a major repair is required is characterized by the probability density function(a) Critics would certainly consider the product a bargain if it is unlikely to require a major repair before the sixth year. Comment on this by determining P(Y > 6).(b) What is the probability that a major repair occurs in the firstyear?

Ste-u/4, y 2 0, S(x) = 10, elsewhere.
