With the setup as in the problem above, we say a group of four people is "interesting", if there are at most five pairs who are friends. AsSsume that each pair of people are friends, independent of every other pair, with probability 1/2. Let N be the number of pairs that are friends in this group. • What distribution does N follow? Poisson O Bernoulli Binomial • What is the probability that a randomly chosen group of four peopie is "interesting"? (Enter your answer as a fraction (recommended) or enter as a decimal accurate to nearest 0.001.) T (N 5) =
