SOLUTION: I am not sure what to use since they are asking for a probabilty that "none fail". It reads: An alarm system has ten fail-safe components. The probability of each failing is .07.

Question 326578: I am not sure what to use since they are asking for a probabilty that "none fail". It reads:
An alarm system has ten fail-safe components. The probability of each failing is .07. What is the probability that none will fail?
I have made it this far...
n=10
p=.07(?)
I don't know where to go from here.

fail: 0.07
not fail: 1-0.07=0.93

P(all not fail) = (0.93)^10 = 0.483982307

48.398% chance of all 10 not failing
