Question

Based on a​ survey, 35​% of likely voters would be willing to vote by internet instead of the​ in-person traditional method of voting. For each of the​ following, assume that 13 likely voters are randomly selected.What is the probability that exactly 10 of those selected would do internet​ voting?

Answer 1

P(X = 10) = (13 choose 10) * 0.35^10 * 0.65^(13-10)

= 286 * 0.35^10 * 0.65^3

= 0.1017
