A company that explores for oil in the ocean is considering two new sites, A and B. The exploration will take the entire year. The company estimates the probability of finding oil is 0.19 at site A and 0.03 at site B. The sites are far enough apart so that whether or not oil is found at one site is independent of it being found at the other. Round your answers to three decimal places, and use four decimal places in any interim calculations. Find the probability that the company will find oil at both sites: .006 Hint: Try making a probability table. only one of the sites: .163 neither of the sites: least one of the sites:

It is equally probable that two signals reach a receiver at any instant of the time T. The receiver will be jammed if the time difference in the reception of the two signals is less than T. Find the probability that the receiver will be jammed.

The data represent the results for a test for a certain disease. Assume one individual from the group is randomly selected. Find the probability of getting someone who tested positive, given that he or she had the disease. The probability is approximately (Round to three decimal places as needed.)

Jack has just been given a ten-question multiple choice quiz in history class. Each question has five answers, of which only one is correct. Since Jack has not attended class recently, he does not know any of the answers. Assuming Jack guesses randomly on all ten questions, find the probability that he will answer six or more of the questions correctly and avoid an F.

Charlie is about to take two laps in the school swimming pool. The time of his first lap is X minutes,  where X is an Exponential(1) random variable. The time of his second lap is Y minutes, where Y is an Exponential(X) random variable. What is the probability that he completes his second lap within one minute?
