The lifetime (in years) ofcar A follows the Weibull distribution with =10 and =0.5. The lifetime (in years) ofcar B follows the Weibull distribution with =8 and =2

1. Find the probability thatcar A dies in the first year.
2. Given thatcar A does not die in the first year, find the probability that itdies in the second year.
3. Find the expected lifetime ofcar A.
4. Which car (A or B) has a higher probability of lasting longer than 1 year?
