Answer:
60
Step-by-step explanation:
5²= 10
10x3=30
90-30=60
 
        
                    
             
        
        
        
I suppose the density is supposed to be

(since  diverges as
 diverges as  , and 0 is conveniently left out of the domain)
, and 0 is conveniently left out of the domain)
For this to be a proper density function, it must be positive (it is) and its integral over the support  must evaluate to 1. We have
 must evaluate to 1. We have

which means  .
.
The distribution function is obtained by integrating the density:

The probability that the component exceeds 2 years in its lifetime is
