Take Off

What is the probability of the taxi and take off at between 275 and 320 minuets?

The taxi and take off for commercial aircraft is a random variable, with an average of 8.5 and a standard deviation of 2.5 minutes. Assuming that the jets are aligned to take off immediately after the other and remove one by one. What is the probability that, for 36 total jets taxi and takeoff time will be between 275 and 320 minutes?

Mean = 8.5 x 36 = 306 Variance = 2.5 * 36 ^ 2 = 225, Std = 15 Now, calculate two scores Z = (320 - 306) / 15 = Z value corresponding to Probability1 Z = (275 - 306) / 15 = Z value corresponding to Probability2 Add to Probability1 Probability2 Here
