assume that 340 tickets are sold such that 220 are sold to individuals (i.e., parties of one) and 120 are sold to 30 groups of four. Each individual group shows up with probability 0.85, and each party of four shows up with probability 0.8540.854. Let X be the random variable counting the number of passengers who show up for their flight. Compute E[X], the expected number of people who actually show up. Express your answer out to one decimal place.
