A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 50.0 and 55.0 minutes. Find the probability that a given class period runs between 51.5 and 51.75 minutes.
Find the probability of selecting a class that runs between 51.5 and 51.75 minutes.
_______ (Round to three decimal places as needed.)
Solution :
Given that,
a = 50.0
b = 55.0
P(51.5 < x < 51.75)
= (51.75 - 51.5) / (55.0 - 50.0)
= 0.25 /5.0
=0.05
Probability = 0.05
