A = Event of being a universal donor.
So:


Solving (a): Mean and Standard deviation.

The standard deviation is:




Solving (b): P(x = 3)
The event is a binomial event an dthe probability is calculated as:

So, we have:




A = 23,000(1 + .03/365)^365(30)
A = 23,000(1.000082192)^10950
The answer is $56,569 or $56,568.92
