Answer:

28

Step-by-step explanation:

The binomial coefficient is calculated as:

nCx=\frac{n!}{x!(n-x)!}

It means that there are nCx ways to select x elements from a group of n elements.

So, If the researcher wants to determine the probability that 6 out of the next 8 individuals in his community are in favor of the president, we can replace n by 8 and x by 6 and calculated the binomial coefficient as:

8C6=\frac{8!}{6!(8-6)!}=28
