Question: A random variable X has the following probability distribution: x P -16 -14 -13 -12 -10 -6 -5 -1 X=x) 0.146 0.208 0.125 0.167 0.063

A random variable X has the following probability distribution:

x P -16 -14 -13 -12 -10 -6 -5 -1

X=x) 0.146 0.208 0.125 0.167 0.063 0.104 0.125 0.063

(The probabilities sum to 1.001 which is acceptable by rounding rules) The expected value of X is

A) -10.819
B) -10.319
C) -11.319
D) 10.319
E)
