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 Px) 1 0.002 0.023 4 0.232 5 0.380 Find the mean of the random variable x. Select te correct choice below and, if necessary, fill in the answer box to complete your choice Round to one decimal place as needed.) The table is not a probability distribution. O B.Explanation / Answer
1) As the total sum of all the probabilities is not equal to 1, so the table is not a probability distribution.
2) As the total sum of all the probabilities is equal to 1, so it is a probability distribution table.
mean = 0 * 0.03 + 1 * 0.08 + 2 * 0.33 + 3 * 0.32 + 4 * 0.14 + 5 * 0.1 = 2.76
