A 4-person grievance committee is to include employees in 2 departments, A and B, with 12 and 28 employees, respectively. If the 4 people are selected at random from the 40 employees, what is the probability of selecting 3 from A and 1 from B? Ten computer circuit boards, including 2 that are defective, are sent to an assembly plant. The plant will select 3 at random and will return the entire shipment if 1 or more in the sample are found to be defective. What is the probability that the shipment will be returned?

As I was driving along the highway to Cleveland, I noticed a speedometer check along the side of the road with posted signs 1 mile apart. I timed us and found that it took us 5 minutes and 45 seconds to travel 5 miles. We had the car set on cruise control, so we were traveling at a constant speed. A while later we passed a sign that said “Akron 76 miles.” At that speed, how long did it take us to drive those 76 miles to Akron? (Convert your decimal answer to an equivalent number of hours, minutes, and seconds. For example, 7.104 hours = 7 hours 6 minutes 14 seconds.)

Arrange these steps in the correct order to prove that if you have an 8-gallon jug of water and two empty jugs with capacities of 5 gallons and 3 gallons, respectively, then you can measure 4 gallons by successively pouring some of or all of the water in a jug into another jug in the correct order. Rank the options below. Fill the 3-gallon jug from the 5-gallon jug, leaving (3, 2, 3). Empty the 5-gallon jug's contents into the 3-gallon jug, leaving (6, 0, 2), and then fill the 5-gallon jug from the 8-gallon jug, producing (1, 5, 2). Fill the 5-gallon jug from the 8-gallon jug, leaving the contents (3, 5, 0), where the ordered triple is used to record the amount of water in the 8-gallon jug, the 5-gallon jug, and the 3-gallon jug, respectively. Top off the 3-gallon jug from the 5-gallon jug, and there will be (1, 4, 3), with four gallons in the 5-gallon jug. Pour the contents of the 3-gallon jug back into the 8-gallon jug, leaving (6, 2, 0). ❤ ← ←
