Two methods, A and B are available for teaching a certain industrial skill. The failurerate is 20% for A and 10% for B. However, B is more expensive and hence is usedonly 30% of the time. A worker was taught the skill by one of the methods but failedto learn correctly. What is the probability that she was taught by method A?Assume D=Method A and DC = Method B; fail = positive(a fraction like a/b., simplify)OP(D)=• P(D)=P(+1D) =P(+1D)=P(+)P(D1+) =(a fraction like a/b.simplify)(a fraction, no decimal,simplify)(a fraction, no decimal.simplify)(a fraction, no decimal)(a fraction, no decimal)

A factory uses a specific machine to produce pieces. From previous data, we know that 97% of the time the machine is set up correctly. If this is the case, it produces 95% acceptable (non-defective) pieces. However, if it is not set up correctly, it produces only 40% of acceptable pieces. Q22 A piece produced by the machine is selected. What is the probability that the selected piece is non-defective? Your answer should be in % and have two digits after the period. So, if your answer is 50.002%, enter 50.00. Your Answer:
On the average the traffic pattern at an intersection is as follows: • Twice as many cars go through as the number of vans, bicycles and trucks combined. • Twice as many vans go through as the number of bicycles and trucks combined. • Half as many trucks go through as the number of bicycles. Calculate the probability that the next vehicle to go through is a truck or a car. (19/27)
