For either-or probabilities, you add the individual probabilities.
.023 + .023 = ?
For winning on both/all you multiply the probabilities.
.023 * .023 = ?
The first answer is for winning on either one of the plays, while the second is for winning on both ("or more"). From the information I have given you, can you combine the two answers?
An instant lottery game gives you probability 0.023 of winning on any one play. Plays are independent of each other.
If you play 2 times, the probability that you win on one or more of your plays is about? (±0.0001)
Thank you!
