Will give brainliest for a detailed solution to ALL PARTS to this probability problem! Thank you!
The time to failure of a typical household refrigerator has the following PDF:
f(t)=t/a 0≤t≤4 yr
a.) What is the value of a?
b.) What is the reliability of the refrigerator for the first year?
c.) What is the probability that a refrigerator will fail during the first month?
