I think I solved the problem correctly, would you please help me verify?
An event has a 1/10 chance of happening. If it was repeated 10 times what would be the probability of the event happening AT LEAST once?
1-(.9)^10 = 65 % chance
is this correct?
Thank you

The chances that the event will not occur the 1st ten times is .9^10 = .34868.
Therefore the chances it will occur at least once is 1-.34868 = .65132 = 65 1%. Yes, you are right on
