Examine the following table. x12345P(x)0.20.30.40.10.05Does this table represent a probability distribution? Explain your answer.

For a probability distribution, all probabilities must add up to 1. Here, 0.20 + 0.30 + 0.40 + 0.10 + 0.05 = 1.05, which is greater than 1. So this is not a probability distribution; choice C says the sum is more than one.
