Question

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 50.0 and 52.0 minutes. Find the probability that a given class period runs between 50.5 and 51.0 minutes.

Answer 1

0.25

Step-by-step explanation:

The easiest way to answer this question is to recognize that a uniform probability distribution is essentially a rectangle with an area equal to 1.

Now find the area of a portion of this rectangle.

`(51-5.05)/(52-50) =(0.5)/(2) =0.25`

• 
  `1*0.25=0.25`
