Suppose that in the small state of Rhode Island in the USA, the average number of women suffering severe osteoporosis (due to the consumption of dairy products) in any given month is 12. What is the probability that in just one-quarter of a month there will be eight (8) women found suffering severe osteoporosis?
Yes, because (0.63)(0.63) = 0.497 No, because (0.63)(0.63) ≠ 0.497 Yes, because 63% + 63% = 49.7% No, because 63% + 63% ≠ 49.7%
The television show Pretty Betty has been successful for many years. That show recently had a share of 19, which means, that among the TV sets in use, 19% were tuned to Pretty Betty. An advertiser wants to verify that 19% share value by conducting its own survey, and a pilot survey begins with 14 households have TV sets in use at the time of a Pretty Betty broadcast. Find the probability that none of the households are tuned to Pretty Betty. P(none) = Find the probability that at least one household is tuned to Pretty Betty. P(at least one) - Find the probability that at most one household is tuned to Pretty Betty. P(at most one) - If at most one household is tuned to Pretty Betty, does it appear that the 19% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Pretty Betty unusual?) no, it is not wrong O yes, it is wrong
A recent survey shows that 16% of college students have dogs and 38% have an HBO subscription. Assuming these two events are independent, what is the probability that a randomly selected college student has neither a dog nor HBO?

Just before a city referendum on a school budget, a local newspaper polls 450 voters in an attempt to predict whether the budget will pass. Suppose that, unknown to everyone, the budget actually has the support of 52% of the voters. What is the probability the newspaper's sample will lead the newspaper to predict defeat of the referendum, that is, what is the probability that the newspaper's sample results in a sample proportion p̂ less than 0.50 in favor of the referendum?
The probabilities are 0.4, 0.2 and 0.3 and 0.1, respectively, that a student uses LAN,Wifi, Prepaid Data, or Hotspot for internet connection. What is the probability thatamong 10 randomly selected students, 2 use LAN, 4 use Wifi, 3 use prepaid data,and 1 uses Hotspot for their internet connection?
HI! HELP ME WITH THIS PLEASE. THANK YOU VERY MUCH! The following hybrids are produced when white snowy owls are mated with brown barn owls: white barn owls, brown snowy owls, white snowy owls, and brown barn owls. The probabilities for each are 1/5, ¼, 9/20, and 1/10, respectively. If 9 owls are selected from this batch, find the probability that 2 are brown barn owls, 3 are white snowy owls, 1 is a brown snowy owl, and 3 are white barn owls.
A hospital reports that two patients have been admitted who have contracted Crohn's disease. Suppose our experiment consists of observing whether each patient survives or dies as a result of the disease. The simple events and probabilities of their occurrences are shown in the table (where S in the first position means that patient 1 survives, D in the first position means that patient 1 dies, etc.). Simple Events Probabilities SS 0.52 SD 0.20 DS 0.14 DD 0.14 Find the probability that both patients survive.
