Answer:
The mean is 4.5 and the standard deviation is 1.44.

An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The mean of the uniform probability distribution is:

The standard deviation of the uniform probability distribution is:

Uniformly distributed random variable ranging from 2 to 7.
This means that
.
So


The mean is 4.5 and the standard deviation is 1.44.

Let L represent the number of cups of lemonade that Marcus sold. Then his revenue can be described by ...
0.75L + 0.35(L -5) = 7.05
