an instant lottery game gives you probability .02 of winning on any one play. Plays are indpendent of each other. If you play 5 times, what is the probability that you win at least once.

To determine "eitheror" 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 eitheror probability, you add the probabilities of the individual events. Since all the probabilities are the same, you can just multiply the probaiblity by 5.
