(2+8+3+6+5=24 points) The probability of a person contracting the flu on exposure is 0.4. Let a success be a person contracting the flu. Consider the binomial distribution for a group of 5 people that has been exposed. a. Write down the probability mass function. Make sure to specify the range of x values. b. Compute p(x) for x = 0, 1, 2, 3, 4,5 and present pmf in the table. c. Based on the probability distribution from (b), draw a histogram for the distribution. What is the shape of the histogram (skewed right/left, bell shaped symmetric, uniform)c. Based on the probability distribution from (b), draw a histogram for the distribution. What is the shape of the histogram (skewed right/left, bell shaped symmetric, uniform) d. Find the cdf, F(x) and sketch its graph. e. Find the mean and the standard deviation of distribution
