Using probability concepts, it is found that:
a) The missing value is 0.04.
b) The mean is of 0.37.
The distribution is given by:
Item a:
The sum of <u>all the probabilities has to be 1</u>, that is:
Thus:
The missing value is 0.04.
Item b:
The mean is given by the <u>sum of each outcome multiplied by it's probability</u>, thus:
The mean is of 0.37.
