How many times does a person need to repeat singing a 25 seconds song so that the probability of at least two of the times the recorded song be exactly the same between them is 90 percent?

Can probability be higher than 100 percent... Say you have 4 oil wells each with a 30 percent chance of hitting ...Isn't the calculated probability of one hitting 120 percent?
No. Probability is defined as a number between 0 and 1 (100 percent). If you have four oil wells, each with a probability of hitting being 30%, then the probability of at least one hitting is 100% - (100% - 30%)4, or about 76%.
What is the probability that a 70 percent free throw shooter would make 1 of 2 shots?
The probability the shooter makes both shots is .7 * .7 = .49, and the probability of making neither is .3 * .3 = .09. So the probability of making exactly 1 out of 2 is 1 - .49 - .9 = .42, or 42 percent.
