Hope and Mike were discussing one entry in a probability distribution: P(x) = 0.5 when x = -3 . Hope felt that this entry was okay since the P(x) was a value between 0.0 and 1.0 . Mike argued that this entry was impossible for a probability distribution since x = 3, and negative values are not possible in probability distributions. Who is correct, Hope or Mike? Justify your choice.
