Three switches in an electrical circuit are connected in parallel. The probability of each switch working is P(A) = 0.6, P(B) = 0.7, P(C) = 0.8. What is the probability that at least one switch is working?

Find the probability that none are working and subtract from 1.
Not working: P(A)= .4, P(B) = .3, P(C)= .2
