This random variable X can be modeled with the binomial distribution, with parameters n=10 (the sample size) and p=0.4 (the probability that a adult worker have a high school diploma).
The expected value of X is then the mean of the binomial distribution with the parameters already mentioned.
This is calculated as:
First, let's factor both of these numbers.
256x:
144x:
Both of these numbers contain
, so that would be the greatest common factor. This could also be written as 16x.
