Extracted text: la Calculate the "binomial coefficient" () Answer (Show work to the right) Consider a class of 10 students in a school district with a 20% prevalence of students with special needs. Assuming the binomial distribution is appropriate, what is the probability that exactly 2 of those students have special needs? Answer (Show work to the right) Consider a set of ten separate water samples from a region where the prevalence of bacterial contamination is 30%. On average, what is the number of samples that will indicate contamination? Answer id To show your understanding of the binomial distribution, write out a very simple equation (with letters) and then fill it in with numbers to show how to calculate the answer you gave in part c)
