Problem #10: Suppose that the waiting time
x
(in seconds) for the pedestrian signal at a particular street crossing is a random variable with the following pdf.
f(x)={((7)/(65)(1-(x)/(65))^(6),0<=x<65),(0 otherwise ):}
If you use this crossing every day for the next 10 days, what is the probability that you will wait for at least 10 seconds on exactly 2 of those days? Problem #10: Round your answer to
4
decimals.
