There is a 20% chance that regular email contains flagged words. A security company estimates that 4.9% of emailsare phishing scams. An email just came through that contains a flagged word. What are the chances that it is a phishing scam? (Enter theprobability as a decimal rounded to four decimal places.)

Suppose that historically, 66% residents in an apartment building own at least one pet. If there are currently 375 residents in the apartment, what is the probability that less than 328 will own at least one pet?
Nationally, 83% of Americans have earned a high school diploma. We want to see if the proportion of Pennsylvania high school students who have a high school diploma is greater than 83%. Suppose a representative sample of 225 Pennsylvanians is taken and each is asked if they have earned a high school diploma. The probability of a sample proportion this high from a population where the true proportion of Pennsylvanians with a high school diploma is 83% is 0.0228. How convincing is this probability in convincing us that the true proportion of Pennsylvanians with a high school diploma is greater than 0.83?
