Six batteries are needed in the production of toy trucks. The quality assurance department requires that each truck be tested before it gets boxed for distribution. During this test, if one of the batteries is dead, the toy truck will not function and would have to be reworked and be sent back. Assume that the batteries are obtained from a large lot that consists of 20% dead batteries. Calculate the probability that a toy would have to be reworked. What is the probability that out of five toy trucks, two will not function?

Your son is a teacher in a state university. As per her class rule, the probability of not getting an additional points for a major examination is 2/3. If there are three engineering students to be selected at random, evaluate the probability that at least one of them gets additional points.
A study tracked a large group of people for 10 years. At the start of the study, 20% were heavy smokers (H), 30% were light smokers (L), and 50% were non-smokers (N). The interest of the study was whether the people in the study died during the study (D) or not die (Dc ). The probability that a light smoker died during the study was twice that of the probability of a non-smoker dying. Also, the probability that light smoker died during the study was half that of the probability of a heavy smoker dying. A randomly selected person from the study died during the study. What is the probability that this person was a heavy smoker (given they died, what is the probability they were a heavy smoker H)?

A local jam production company is confident that 60% of the population will like its new grapefruit jelly. If 200 persons taste the new grapefruit jelly, determine the number of persons who are expected to like it. From a random sample of 10 persons who tasted the new grapefruit jelly, calculate the probability that less than two will like it.
Brgy. Pallet has one Full Restore and one Max Revive available for emergencies. The probability that the Full Restore is available for use is 0.98 and the probability that the Max Revive is available for use is 0.92. Assuming that the availability of these items is independent of each other, what is the probability that both of these items are available for a Trainer to use?

A manufacturer makes two models of an item: model I, which accounts for 75% of unit sales, and model II, which accounts for 25% of unit sales. Because of defects, the manufacturer has to replace (or exchange) 5% of its model I and 10% of its model II. If a model is selected at random, find the probability that it will be defective. Please round the final answer to 2 or 3 decimal places. P(detective)=
