We're looking here at a uniform distribution.
00:03
We want the values for a and b.
00:06
So these are the parameters of a uniform distribution, and they refer to the beginning and end, respectively, of the interval of possible values this might take.
00:16
So between a and b, every possible value has an equal probability, like so, and then outside of this interval, probability is just zero.
00:27
So what is a and b? but we're told it takes between 90 seconds, and 16 minutes.
00:32
But we need this in minutes.
00:37
So b, the end of the interval, is quite easy.
00:39
It's just 16.
00:41
A is 90 seconds, which is 1 .5 minutes.
00:48
So that's the interval.
00:51
Next, we want the mean time to resolve the problem.
00:56
So i was called it's part i.
00:58
So the mean or expected value of a uniform distribution is a plus b over 2...
