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!

For eitheror 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?
