Explanation:

We can solve this problem using concepts of the binomial probability distribution.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability. Has a mean of

In this problem, we have that

40 percent of all individuals have group a blood. This means that .

If six individuals give blood, find the mean number of individuals having group a blood.

We work with six individuals, so .

The mean is:

The mean number of individuals having group a blood is 2.4 individuals.
