At a new exhibit in the Museum of Science, people are asked to choose between 73 or 175 random draws from a machine. The machine is known to have 98 green balls and 61 red balls. After each draw, the color of the ball is noted and the ball is put back for the next draw. You win a prize if more than 70% of the draws result in a green ball. [You may find it useful to reference the z table.] a. Calculate the probability of getting more than 70% green balls. (Round your intermediate proportion values and “z” value to 2 decimal places, and final answer to 4 decimal places.) b. Would you choose 73 or 175 draws for the game?

According to an airline, flights on a certain route are on time 85% of the time. Suppose 17 flights are randomly selected and the number of on-time flights is recorded. (a) Explain why this is a binomial experiment. (b) Find and interpret the probability that exactly 12 flights are on time. (c) Find and interpret the probability that fewer than 12 flights are on time. (d) Find and interpret the probability that at least 12 flights are on time. (e) Find and interpret the probability that between 10 and 12 flights, inclusive, are on time.
