System A has a 10% chance of being "down", while system B has a 5% chance of being "down".
What is the probability that:
1) Neither computer system will be operational.
2) Both computer systems will be operational.
Thanks!

PsyDAG,
1) If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
.05 * .10 = ?
2) .95 * .90 = ?
