Question

Experience has shown that 20% of all persons afflicted by a certain illness recover. A drug company has developed a new medication. Ten people with the illness were selected at random and received the medication.

Suppose that the medication was absolutely worthless. Let X be the number of patients who recovered from the illness.

Part 1. Construct and present the probability distribution of X using a probability distribution table:

In the first column, identify the possible values of the random variable . Arrange your values in ascending order (start from the lowest to the highest value).
In the second column, compute the probability values, . Express the values in decimal form and round off to two significant figures.
