Expert Answer

Step 1

The given information is not sufficient to solve all the subparts. More information is required to solve Part (G). So, we will answer first two subparts.

Step 2

E) Obtaining the probability distribution of X:

It was found that 20% of the time, Melvin misses and does no damage, 70% of the time he hits and does 8 damage and 10% of the time he hits and does 12 damage.

The random variable X denotes the amount of damage Melvin does in a single swing.

That is, the random variable X takes values 0, 8 and 12 with probabilities 0.20(=20%), 0.70(=70%) and 0.10(=10%) respectively.

The probability distribution of a random variable X is the set of all possible values of the random variable X and its corresponding probabilities.

From the given information, the probability distribution of X is obtained and is given in the following table:

Step 3

F) Obtaining the mean, variance and standard deviation of X:

The mean value of a discrete random variable X is given by,

E(X) = µx = ∑x.P(...
