Question

An alarm system has six fail-safe components. The probability of each component failing is 0.05 (5%).

What is the probability that all 6 components are in working order?

Answer 1

you take the % for a component to work which is 1-.05= .95 or 95%

 

Next put the decimal to the 6th power:

 

(.95)^6=

 

0.73509189062 or 73.509189062%
