Suppose a statistics professor never lets their class out early. The time that they can let their class out is anywhere from 0 minutes to 10 minutes late and all minutes are equally likely.
What is the probability the professor lets the class out from 3 to7 minutes late?

sounds like a uniform distribution

@amistre64 yes, but I don't know how to solve the probability the professor lets the class out from 3 to7 minutes late?

my answer is A=B.H (4.1)= 4

amistre64 · Answer

well a uniform distribution is just a stright line that forms a rectangle from 0 to 10 in this case

the probability of all evernts has to eqaul 1 so that area of the rectange has to equal 1, and my draw button is not clicking ...

----------------------
|                                       | h
|                                       |
----------------------
0                                     10

how do we determine that value of h?
