SOLUTION: Suppose the reaction time x (in minutes) of a certain chemical process follows a uniform probability distribution with 5≤x≤15 . Find the probability that the given reaction ti

Take the time duration, which is over 5 minutes: it is  (7 min - 5 min) = 2.0 minutes,

and relate it to the duration of  the basic time interval of (15 min - 5 min) = 10 minutes.


So, the ratio   =  = 0.2 = 20%  is the sough probability.


It is how the uniform probability distribution works.
