The following table presents the probability distribution of the number of defects X in a randomly chosen printed circuit board.

a. Find P(2).

b. Find P(1 or more).

c. Find the probability that at least two circuits are defective.

d. Find the probability that no more than two circuits are defective.

e. Compute the mean μX.

f. Compute the standard deviation σX.
g. A circuit will function if it has no defects or only one defect.
What is the probability that a circuit will function?
