8. Circuit boards are made by machines A, B, C and D. Machine A makes 15% of the components, machine B makes 30%, machine C makes 35% and machine D makes the remainder. The probability that a board is acceptable is 0.93 when made by machine A, 0.96 when made by machine B, 0.95 when made by machine C and 0.93 when made by machine D. A board is picked at random. Calculate the probability that it is made by machine D and is unacceptable O a. a. 0.014 0.012 O b. C. 0.1395 d. 0.3325 O
