Abstract

cannot be answered

Multiple Choice

Yes, because all of the probabilities are between 0 and 1 inclusive and the sum of all the probabilities is 1.

No, some of probabilities are not between 0 and 1 inclusive

No, the sum of all the probabilities is not 1.

Yes, because the distribution is symmetric
