Over the last few years, the Grand Canyon has had an average of 6.2 million visitors each year. During that period, an average of 12 people per year have died while visiting the park due to accidents and natural causes. Assuming these figures are current, what is the probability that a visitor to the Grand Canyon will die while visiting in a given year? (Round your answer to eight decimal places.) Is your answer empirical or theoretical? O empirical O theoretical 11. [-/2 Points] DETAILS The silver urn contains five black balls and two brown balls. The golden urn contains three red balls, nine yellow balls, and six blue balls. If I choose a ball from the silver urn and a ball from the golden urn, what is the probability that I get a black ball and a yellow ball? Express your answer as a decimal rounded to 3 decimal places. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER In one study, researchers at a clinic looked at more than 120,000 patients enrolled in 14 international studies in the past 10 years. Among the patients with heart problems, researchers found at least one risk factor in 84.8% of the women and 80.8% of the men. If a woman is selected at random from the women with heart problems, what is the probability she has none of the risk factors? Write your answer as a percentage. Hint: The opposite of "none" is "at least one"! 15.6 % If a man is selected at random from the men with heart problems, what is the probability he has none of the risk factors? Write your answer as a percentage. 19.6 X % Shipping constitutes a large part of the budget for online retailers. One such retailer ships fragile items that occasionally get broken and have to be replaced/re-shipped. Historically, 7% of these items have gotten broken during shipping. (a) If an item is shipped, what is the probability that it does not get broken? In other words, what is P(not broken)? Express your answer as a decimal rounded to two decimal places. (b) If the retailer ships 3 separate items, what is the probability that none will be broken during shipping? Express your answer as a decimal rounded to three decimal places.
