In a large population, about 45% of people prefer tea over coffee. A researcher takes a random sample of 13 people and surveys whether they prefer tea over coffee. Use the binomial distribution to compute the probability that exactly 6 of the people in the sample prefer tea over coffee. Identify the following information required to find the probability of people who prefer tea over coffee. Provide your answer below: n = trials x = successes p = probability of those who prefer tea   P(x)=
