t they have swer own, ie. EC 6. For the following scenarios determine the type of probability distribution: Binomial, Hypergeometric, Poisson or None of these What is the probability of seven or more heads in 10 tosses of a fair coin? b. a. certain Starbucks has on average 5 customers per minute. What is the probability that 12 Given a lot with 21 good units and 4 defectives, what is the probability that a sample of five will Four companies are bidding for each of the three contacts, with specified success probabilities. Suppose you first randomly sample one card from a deck of 52. Then, without putting the card A customers arrive in Starbucks in a 30-minute time interval. yield no more than one defective? What is the probability that a single company will receive all the orders? c. d. e. back in the deck you sample a second and then (again without replacing cards) a third. Given this sampling procedure, what is the probability that exactly two of the sampled cards will be aces (4 of the 52 cards in the deck are aces). f. The switchboard in a small Denver law office gets an average of 2.5 incoming phone calls during the noon hour on Thursdays. Staffing is reduced accordingly: people are allowed to go out for during that hour. What is the chance that 6 calls will be received in the noon hour, some particular A company makes electronic components for TV's 95% pass final inspection (and 5% fail and lunch in rotation. Experience shows that the assigned levels are adequate to handle a high of 5 calls Thursday, in which case the firm might miss an important call? g. need to be fixed). Suppose 120 components are inspected in one day, what is the probability that 10 fail inspection?Explanation / Answer
