According to a police report there were [z] traffic accidents last year in a certain town. Of these [z] accidents, [w] accidents involved speeding, [x] accidents involved alcohol, and [y] involved both risk factors. Denote by A the event that an accident involves alcohol and denote by SP the event that an accident involves speeding. Based on these numbers estimate the probability P(A and SP). Round your answer to 3 digits after the decimal point.

Let X be the number of students taller than 171 cm in a simple random sample of 10 Auburn students.

Suppose that the daily demand for flu shots in a medical center during the flu season is approximately normal with mean 180 and standard deviation 30. Use the Empirical Rule to find approximately the probability that more than 150 flu shots are needed.

Denote by A the event that an accident involves alcohol and denote by SP the event that an accident involves speeding. Based on these numbers estimate the probability that the accident does not involve speeding. Round your answer to 3 digits after the decimal point.

Suppose X is a discrete random variable whose distribution is given by the table below. X 0 1 2 3 4 p(x) [x] [y] 0.10 ? 0.10 Find the probability P(X ≤ 1).

A student from a class of 150 students is randomly selected. The class is composed as follows Freshman Sophomore Junior Senior Male 12 24 10 14 Female 18 36 30 6 You are told that the selected student is a junior. What is the probability that the selected student is also male.

Let X be the litter size for a certain species of animals. Suppose that X has the following distribution. X 0 1 2 p(x) 0.4 0.3 0.3 Find the expected value of X.

Each of the following is true of type 2 diabetes except one. Which one is the exception?
