Let X = amount of time for which on book is taken out of a college
library by a randomly selected student and suppose X has pdf
`f(x)=0.5x,0lexle2`, and
`=0`,otherwise.
Calculate (iii) `P(X>1.5)`

Let X =time (in minutes) that elapser betweeb the bell and the end of the lecture in case of a college professor.Suppose X has a pdf. f(x)=kx^2,0lexle2 and =0,otherwise.(i)Find k.

Let X =time (in minutes) that elapser betweeb the bell and the end of the lecture in case of a college professor.Suppose X has a pdf. f(x)=kx^2,0lexle2 and =0,otherwise.(iii)What is the probability that lecture continues for atleast 90 seconds beyond the bell?
