6.3 question 3 b

6.1.5 Question Help Let X be the number of languages in which a person is fluent. For residents of a certain region, this has a probability distribution P(0) = 0.02, P(1) = 0.83, P(2) = 0.15, with negligible probability for higher values of x. a. Explain why it does not make sense to compute the mean of this probability distribution as (0 + 1 + 2)/3 = 1.0. b. Find the correct mean. a. Choose the reason why the mean is not the simple average of the possible values. A. The probabilities of each possible value are not all the same. O B. The mean should be computed by averaging the probabilities, not the possible values. O G. There are not enough possible values of x to compute the mean. O D. The possible value of 0 skews the mean when computed in this fashion. b. The mean is languages. (Type an integer or a decimal. Do not round.)
