Suppose 40% of the restaurants in a certain part of a town are in violation of the health code. A health inspector randomly selects five of the restaurants for inspection. (Round your answers to four decimal places.) (a) What is the probability that none of the restaurants are in violation of the health code? (b) What is the probability that one of the restaurants is in violation of the health code? (c) What is the probability that at least two of the restaurants are in violation of the health code?

I need help solving this problem: Subjects for the next presidential election poll are contacted using telephone numbers in which the last 4 digits are randomly selected (with replacement). Find the probability that for one such phone number, the last 4 digits include at least one 0.

A certain math conference has 9258 attendees.  Of these individuals, 5371 are college professors, and 4496 are female.  Of the college professors, 3347 are female.  What is the probability that a randomly selected attendee is female or a college professor? Answers should be decimals (not percentages) correct to three decimal places.

Suppose that 19% of people own dogs. If you pick two people at random, what is the probability that they both own a dog?

. Assume that 75 percent of the students at the university have taken 4 years of high school math. Of those with four years of high school math, 80 percent plan to major in science. Of those without 4 years, only 10 percent plan to major in science. You stop a student at random. If the student plans to major in science, what is the probability that this student had four years of high school math?
