Exercise 12.8.1: Probability of manufacturing defects. The probability that a circuit board produced by a particular manufacturer has a defect is 1%. You can assume that errors are independent, so the event that one circuit board has a defect is independent of whether a different circuit board has a defect.

A particular coin is biased. Each timr it is flipped, the probability of a head is P(H)=0.55 and the probability of a tail is P(T)=0.45. Each flip os independent of the other flips. The coin is flipped twice. Let X be the total number of times the coin shows a head out of two flips. So the possible values of X are x=0,1, or 2. a. Compute P(X=0), P(X=1), P(X=2). b. What is the probability that X>=1? c. Compute the...
