Suppose that a DJ has two (2) turntables and one (1) microphone. If the failure rate of a single turntable is 2% and the failure rate of a microphone is 1.5%, what is the probability that none of the DJ's equipment fails at a show? A game consists of rolling two die and adding the two numbers. Let E be the event "the sum is 4, 5, or 6" and F be the event "the sum is even". Are the events E and F independent? Briefly explain your answer. Three percent of the circuits produced by a machine are defective. What is the probability that a box of 20 circuits contains two or more defective circuits? An insurance company determines that the probability a person files a claim in the next 18. year is %8. If a group of 10 policy holders is chosen at random, what is the probability that none of them file a claim in the next year?

There are two (2) urns, one red one green. Each urn contains red and green marb.es. The red urn has four (4) red marbles and two (2) green marbles; the green urn has three (3) green marbles and two (2) red marbles. An marble is drawn from the green urn, then without replacing the marble, a 2"nd marble is drawn from the urn with the color of the first marble. (a) Draw a tree diagram for this experiment (h) What is the probability the 2nd marble drawn is green?
