A professor gives a test to a large class. The time limit for the test is 50 minutes, and the first student to finish is done in 35 minutes. The professor assumes that the random variable T for the time it takes a student to finish the test is uniformly distributed over [35, 50].

Compute the probability P(T<45 | t>40)

(Enter your answer to one decimal place. For "0.9", you would write 0.9). Do not round.
