Question 1126773: If the random variable X denotes the real valued outcomes given in the following table with the given frequency of occurrence of each of the outcomes, fill in the last line of the table and find the expected value of X.

Outcome -2 -1 0 1 2
Frequency 23 29 24 23 29
P(X) = ? ? ? ? ?

128 specific events
probability of each is frequency divided by 128
For expected value, multiply outcome * frequency, add them and divide by 128 at the end
-46-29+0+23+58
6/128 or about 0.047
