You are running a Bernoulli Trial and X represents the number of trials until the first success. Which best describes the expected value of X? The number of trials until the first success. The average of the number of trials until the first success over many trials. The expected probability of a success. The number of successes you expect.

Which of the following best describes the expected value of a random variable X? The most likely outcome of a single trial of the experiment. The probability that the outcome of a single trial is the same as the average. The likely average of the values of X if the experiment is run many times. The probability of the most likely outcome.

An experiment consists of identical trials. Each trial can result in one of two possible outcomes: success or failure. The trials are independent. The probability of success is constant from trial to trial. Let X be a random variable that counts the number of trials necessary to obtain the first success. Show that E(X) = 1/p (without using calculus!)

The expected value of a discrete random variable - is the value it is expected to assume in the next trial. - is the average value for the random variable over many repeats of the experiment. - is the most likely or highest probability value for the random variable. - will always be one of the values X can take on, although it may not be the highest probability value for the random variable.
