Step-by-step explanation:
Binomial distribution formula :-
Given : The probability of that the general population has blood type A =![\dfrac{1}{3}](/tpl/images/0083/7757/fd93e.png)
Sample size : n=6
Now, the probability that exactly three of them have blood type A is given by :-
Therefore, the probability that exactly three of them have blood type A = 0.2195
