Suppose the time to failure in hours of certain electronic components subjected to continuous vibrations is found to be a weibull random variable with κ=1.1,and λ=1/2.

(a) how long should we expect this component to last when we install a new one in a particular system?

(b) given that one of these components has already lived to the expected lifetime, what is the probability it will last another 50%of the expected lifetime?

How do you find principle and simple interest
