When calculating probability you need to remember that probability is:
something that you are observing divided by total number of participants.
The number you get is relative value(has value between 0 and 1) and if you want to get it in percentage (more clearly) just multiply it with 100.
In this case we are observing blood type B persons. Number of them is 165.
Total number of persons is 1500. Therefore our calculation looks like this:
165/1500 = 0.11 or the probability is 0.11*100=11%
The equation that would let us determine the number of people or population at a certain year is calculated through the equation,
A(t) = A(o)(2^(t - 1950)/50)
Substituting the known values,
A(t) = (2.5 million people)(2^(2100 - 1950)/50))
A(t) = 20 million
<em>Answer: 20 million people</em>
