2. 4 people are randomly selected and eye color was recorded. Assume each person's eye color is independent of the next and the P(Brown)=0.70, P(Other)=0.30 Let the random variable X be the number of Brown eyed people selected. a. This is a binomial distribution, what is n and p? b. What is the formula corresponding to the binomial probabilities? C. What is the expected number out of 4 people to have brown eyes? d. How many combination of ways is it possible to have exactly half the people having brown eyes? e. Fill in the following probability distribution table X P(X=x)
