To determine *"either-or"* probabilities, you *add* the probabilities of the individual events. Since the probabilities of each event are the same, you could multiply by 5.

I hope this helps. Thanks for asking.

For *either-or* probability, you *add* the probabilities of the individual events. Since all the probabilities are the same, you can just multiply the probaiblity by 5.
