You refer to a rectangular distribution.
I.e. Area ∝ probability
so, length x height = area
=> 6 x height = 1
so, height = 1/6
Therefore, greater than 2.25 minutes => 8-2.25 = 5.75 minutes
=> 5.75 x 1/6 = 0.9583
Since this is uniformly distributed, there is no need to
find the height or standard deviation.
Answer:

Step-by-step explanation:

A = 2/-3 which is -0.6666...
and b= 1/4.
so what you want to do is -0.66666666666 * 2 = -1.33333333333
then you want to do -1.33333333333 + .24 = (-1.093333333) is your answer
Answer:
1 (6/6)
Step-by-step explanation:
because 1/3 will turn into 2/6 so when you add them it will be 6/6 :)
