Let \(X\) be a discrete random variable with the stated value set

The table below lists the complete value set and its probabilities

Value of XProbability
\(-3\)\(\frac{11}{24}\)
\(-2\)\(\frac{1}{8}\)
\(3\)\(\frac{1}{8}\)
\(6\)\(\frac{7}{24}\)
(a)1 mark

Decide whether this table satisfies the two defining properties of a discrete probability distribution

(b)1 mark

Choose the statement that matches the two checks
