Quality control: A population of 586 semiconductor wafers contains wafers from three lots. The wafers are categorized by lot and by whether they conform toa thickness specification, with the results shown in the following table. A wafer is chosen at random from the population. Write your answer as a fraction or adecimal, rounded to four decimal places.LotConformingNonconformingA8912B1732925528Send data to Excel(a) What is the probability that the wafer is from Lot C?(b) What is the probability that the wafer is conforming?(c) What is the probability that the wafer is from Lot C and is conforming?(d) Given that the wafer is from Lot C, what is the probability that it is conforming?(e) Given that the wafer is conforming, what is the probability that it is from Lot C?(f) Let E, be the event that the wafer comes from Lot C, and let E, be the event that the wafer is conforming. Are E, and E, independent?

In roulette, a wheel is divided up into slots of equal area. each slot is labeled with one of the numbers from 0 through 36, and one slot is labeled with a 00. half the slots are red, and half the slots are black. when the wheel is spun, it lands on one of these slots.( the problem is complete.) (a) if the wheel is spun three times, find the probability it lands on a 17 twice, and then a red slot.(b) if the wheel is spun three times, find the probability it does not land on the 00 slot all 3 times.(c) if the wheel is spun three times, find the probability it lands on a slot other than 00 all three times.

3. Probability is a branch of mathematics that deals with calculating the likelihood of a given event's occurrence, which is expressed as a number between 1 and 0. i. If a fair 6-sided die is rolled once. If A is the event of "rolling an odd number," write out A and A° а. b. If A = {1,2,3,4} and B = {4,5,6}, write out A°, B°, AB, and AUB. i. When two fair die are thrown together: a. What is the probability that the dice total is 4?
Two unbalanced dice are thrown at the same time. The first die has the property that the probability of getting a side of 1 and 6 is three times the other side.
