in a certain weather forecast the chances of thunderstorm is stated as 18%. express the indicated degree of likelihood as a probability value between 0 and 1 inclusive

The probability of an event occurring is 3/7. Determine the odds against the event occurring.

A region averages 1.5 droughts per decade. What is the probability of getting 5 droughts in the next 30 years? 5 droughts in 30 years is very close to the average value of 4.5 in 30 years. Explain why the probability you got above makes sense. What is the probability of getting at least 1 drought in the next decade?

Suppose that 68% of people own dogs. If you pick two people at random, what is the probability that they both own a dog? Give your answer as a decimal rounded to 4 places.

The probability of passing the bar exam in a certain state is 2/3. If 10 people passed the test at a college in that state, then find the most likely value for the number of people who failed the test at that college.

In the winter, guests who visit Yosemite National Park like to stay at an overnight lodge in the park 66 % of the time. Find the probability that among 7 guests surveyed exactly 5 guests like to stay at an overnight lodge in the park.P(x = 5)

According to a 2009 Reader's Digest article, people throw away approximately 17% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 114 grocery shoppers to investigate their behavior. What is the probability that the sample proportion is between 0.09 and 0.15? Answer = (Enter your answer as a number accurate to 4 decimal places.)

Suppose that the probability of a plane arriving on time is 80%. Out of ten flights, what is the probability that at least seven will arrive on time? Explain your reasoning.

According to a 2009 Reader's Digest article, people throw away about 9% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 180 grocery shoppers to investigate their behavior. What is the probability that the sample proportion does not exceed 0.15? (Enter your answer as a number accurate to 4 decimal places.) Answer =
