I have 3 products I tested for 1000 hours each with no failures. I will be using 8 of these products for 800 hours a year (each) for 5 years, I need to know the probability of 1, 2, or 3 failing, I also need to know the overall MTBF. Everytime I try to calculate it I get infinity so I am trying to find the lower bound with a certain degree of confidence, 95%, but I am also having difficulty finding a calculation that suites my test data.
Can anyone help me out there?
