Question

Ted is not particularly creative. He uses the pickup line "If I could rearrange the alphabet, I'd put U and I together." The random variable x is the number of girls Ted approaches before encountering one who reacts positively. Determine whether the table describes a probability distribution. If it does, find its mean and standard deviation. Find the mean mu of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. mu = (Round to one decimal place as needed.) The table is not a probability distribution.

Explanation / Answer

We need to add the p(x) values and see if they add up to 1 for it to be a probability distribution.

.001+.011+.127+.253+.455=0.847

thus answer B is correct, it is not a probability distribution
