I need help with the following problems

1.If it is possible for the events A and B to occur simultaneously, then P(A or B)=jQuery20007111587535347634_1519267704760

2.Find the indicated probability. If P(A and B)equals=0.30.3, P(A)equals=0.60.6, and P(B)equals=0.50.5, find P(A or B).

3.If P(AB)equals=0.8, P(A)equals=0.4, and P(AB)equals=0.35, find P(B). Assume that A and B are events.

4.The manager at the local auto shop has found that the probability that a car brought into the shop requires an oil change is 0.75, the probability that a car brought into the shop requires brake repair is 0.25, and the probability that a car requires both an oil change and brake repair is 0.13. For a car brought into the shop, determine the probability that the car will require an oil change or brake repair.

5.The windshield wipers on a car have not been working properly. The probability that the car needs a new motor is 0.5, the probability that the car needs a new switch is 0.4, and the probability that the car needs both is 0.2. What is the probability that the car needs neither a new motor nor a new switch?

6.A cooler at a picnic contains 100 cans of soda covered by ice. There are 37 cans of cola, 13 cans of orange soda, 26 cans of ginger ale, and 24 cans of root beer. The cans are all the same size and shape. If one can is selected at random from the cooler, determine the probability that the soda selected is orange soda, root beer or cola.

7.A manufacturer has shipped 47 cameras to an electronics store, of which 33 are defective. If the electronics store sold 21 cameras before discovering that some were defective, what is the probability that at least one defective camera was sold?

8.A sushi restaurant has prepared 30 portions of seafood, five of which had been left out too long and spoiled. If 8 of the 30 portions are served randomly to customers, what is the probability that at least one customer will receive spoiled food?

9.A shipment of 60 inexpensive digital watches, including 6 that are defective, is sent to a department store. The receiving department selects 10 at random for testing and rejects the whole shipment if 1 or more in the sample are found defective. What is the probability that the shipment will be rejected?
