the book gave me the answer but i have no idea how to obtain that answer. heres the problem:
RH type Groups
O A B AB
Positive 39 35 8 4
negative 6 5 2 1
The given data suggests that 40% of the population consists of people with group A blood. If 10 people are randomly selected from the general population (instead of the sample of 100 people in the given table), find the probability that they all have group A blood.
Like what is the general population first of all? Anyways, the book gave me the answer: 0.000105
Thanks for your time

40% is 2/5 and you're finding 10 people with group A blood. Disregard the chart since its asking for the general population.
(2/5)^10 is the same as (2/5)(2/5)(2/5)... 10 times and you get the answer .000105
I just did this problem just now :P you in biostats too?! haha
