D E F G H K M N Often, critical systems in a variety of applications are set up in parallel to avoid catastrophic failure (for example, military or medical applications). Consider a system with 5 critical but highly sensitive components running in parallel. As long as one of these components functions, the system remains operational. The probability that one of the parallel components fails is 0.125, and the probability of failure of one component is independent of another. a) Parameter value(s) and distribution (using @Risk) A B C 1 2 3 4 5 6 7 8 9 Distribution 10 Parameter(s) 11 b) Use Excel and @Risk to determine the probability of system failure. c) Excel function From @Risk (paste graph below confirming your answer) 12 13 14 15 16 17 18 19 20 21 22 P R S T Use Excel and @Risk to determine the probability of 3 or more components failing.
