Question: A probability distribution can be written in formula notation such as P(X)= 1/X, where X = 2, 3, 6. The distribution is shown as follows:

A probability distribution can be written in formula notation such as P(X)= 1/X, where X = 2, 3, 6. The distribution is shown as follows:

X P(X) 2112 2 3 22/12 1 3 6 6

For Exercises write the distribution for the formula and determine whether it is a probability distribution.

P(X) = X/(X + 2) for X = 0, 1, 2

X P(X) 2112 2 3 22/12 1 3 6 6
