Step 4 Reliability is 16 x .04. So step 4 Reliability is .64

Problem 2: Reliability (18 points). Please show all work, or you may not receive full credit. Please calculate all reliability numbers out to three digits (e.g., .009). Suppose that I have a 4-step system. For Step 4 Reliability, do the following: multiply Class # by .04, that is Step 4's reliability. Step 1: .95 Step 2: .95 Step 3:.95 2a What is the reliability of the system if all four steps have to work? (8 points) 2b Suppose that I've made improvements to the system. Now, it will work if at least 3 of the 4 steps work. What's the new reliability of the system? Keep three digits (example, .026, don't round to .03) in your reliability calculations, please.
