Question

1. In 2023, Southwest Airlines had 76% On-Time Percentage (OTP) for flights. Suppose 4 flights are randomly selected from Southwest Airlines, find the probability of each: a) All four are On-time ($x = 4$). b) None of the four are On-time ($x = 0$). c) At least one is On-time ($x \ge 1$). 2. Fantasy 5 California lottery has a top prize for matching all 5 of 5 numbers picked between 1 and 39. If you choose one combination, what's the probability it's the winner? 3. The given probability distribution describes customer ratings for a kitchen vented range hood at Home Depot. Find: Stars (x) Ratings P(x) 5 42% 4 33% 3 15% 2 1% 1 9% a) Expected value (mean average) b) Standard deviation (SD = sigma) c) Lower and Upper Normal limits
