Question: Let X = the time it takes a read/write head to locate a desired record on a computer disk memory device once the head has

Let X = the time it takes a read/write head to locate a desired record on a computer disk memory device once the head has been positioned over the correct track. If the disks rotate once every 25 milliseconds, a reasonable assumption is that X is uniformly distributed on the interval [0,25]. a) Write the pdf for X. b) Find P (10 s X $20). c) Find P (X 210). d) Find the cumulative distribution function, F(X). e) Find the expected value and standard deviation of X
