QUESTION:
Only 60% of certain kinds of seeds germinate when planted under normal conditions. Suppose that four such seeds are planted, and X denotes the number of those that will germinate. Find the probability mass functions of X and Y = 2X + 1.
ANSWER:Step 1 of 3
Let us consider is the number of successes (where germination denotes successes) in a trial of seeds, and the germination probability is , thus Thus
