Question

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 49.0 and 59.0 minutes. Find the probability that a given class period runs between 50.5 and 51.25 minutes.

Answer 1

To find the probability of the statistic class that it could be done at the period at 50.5 and 51.25 minutes and not their usual duration of 49 and 49 minutes so to get the probability you must subtract the time and would come up with 0.75 minutes and then divide it by 10 so the probability is 0.075
