New York State’s "Quick Draw" lottery moves right along. Players choose between one and ten numbers from the range 1 to 80; 20 winning numbers are displayed on a screen every four minutes. If you choose just one number, your probability of winning is 20/80, or 0.25. Lester plays one number seven times as he sits in a bar. What is the probability that all seven bets lose?

A robotic insertion tool contains 17 primary components. The probability that any component fails during the warranty period is 0.01. Assume that the components fail independently and that the tool fails if any component fails. What is the probability that the tool fails during the warranty period? Round your answer to four decimal places (e.g. 98.7654).

Timber beams are widely used in home construction. When the load (measured in pounds) per unit length has a constant value over part of a beam, the load is said to be uniformly distributed over that part of the beam. Consider a cantilever beam with a uniformly distributed load between 90 and 105 pounds per linear foot. a. What is the probability that a beam load exceeds 99 pounds per linear foot? b. What is the probability that a beam load is less than 92 pounds per linear foot? c. Find a value L such that the probability that the beam load exceeds L is 0.4.

A hare and a tortoise compete in a race over a course 1.50 km long. The tortoise crawls straight and steadily at its maximum speed of 0.290 m/s toward the finish line. The hare runs at its maximum speed of 7.55 m/s toward the goal for 1.200 km and then stops to tease the tortoise. How close to the goal can the hare let the tortoise approach before resuming the race, which the tortoise wins in a photo finish? Assume that, when moving, both animals move steadily at their respective maximum speeds.

Suppose a certain candy is made up of red, yellow, green, blue, and orange pieces. a) If you draw one piece of candy, are the events of getting a green one and getting a yellow one disjoint, independent, or neither? b) Assume you have an infinite supply of these candy pieces from which to draw. If you draw two pieces one right after the other, are the events of getting a blue on the first and a blue on the second disjoint, independent, or neither? c) Can disjoint events ever be independent? Explain.

A study sampled 350 upperclassmen (Group 1) and 250 underclassmen (Group 2) at high schools around the city of Portland. The study was performed at the end of the school year and asked each if they had used steroids at any point in the last school year. Of the upperclassmen, 23 claimed to have used steroids in the last school year, and of the underclassmen, 21 claimed to have used steroids. Run a 95% confidence interval to test for a significant difference in the proportions of students who used steroids. Enter the confidence interval - round to 3 decimal places.

Elliott is counting the change from a class fundraiser. He has half as many quarters as nickels, and he has 7 fewer dimes than nickels. The total value of coins is $5.90. He wrote the equation 0 Which statements identify Elliott’s errors? Check all that apply. He should have written the expression for the number of dimes as x – 7. He should have written the coin values as 5, 10, and 25 and not as 0.5, 0.10, and 0.25. He should have written the coin value for the nickel as 0.05. He should have translated the scenario as value of all dimes = value of all nickels and value of all quarters = value of all nickels. He should have written the expression for number of nickels as 2x.
