What is the formula for figuring out the percentage chance if there are mulitple times at same %

[From: ] [author: ] [Date: 12-05-15] [Hit: ]
..but I dont have that on my calculator and I was wondering how with just plain old math I could have a set formula for figuring out any initial % chance then figure out how much it is after how ever many times it is repeated...-By using plain old math,......
For example if there is a 50% chance of something happening 1 time.

Then for that to happen 2 times in a row the odds are only 25%

Then for that to happen 3 times in a row the odds are 12.5%
Etc.....

but what if the initial % is 95% (or whatever number)

I know there is a symbol used sometimes that looks like this "^"
but I don't have that on my calculator and I was wondering how with just plain old math I could have a set formula for figuring out any "initial %" chance then figure out how much it is after how ever many times it is repeated...

By using plain old math, just take the number and multiply it by itself the number of times you want to show.
So flipping a coin 4 times, the chance of getting heads everytime is
50%*50%*50% %50%
Its better to do it as decimals when using a calculator, and multiplying the result by 100. The same can work for other numbers
0.95*0.95 is the chance of two things happening that both have a 95% chance of happening, provided the events dont affect each other.

The ^ symbol you are talking about is a to the power of symbol, which can be found on your calculator. Its the x^y button, the y will be small to the top right of the x. It might also be a white box instead of a y. Put the number of times you want in there. So the first example would be 0.5^4, because there are 4 0.5s.

The chance of a 0.95 event happening 10 times for example is 0.95^10 = 0.599 or roughly 60%

"^" Is an exponent symbol. It's on our keyboards, not the calculator. To do it on a calculator it would look like an x, with a little y at the top right of the x. This is the exponent button.

You would hit 0.95, wich would be 95%, then the exponent button, then how ever many times it happens. For instance, for the percent chance of it happening three times in a row, you would hit "3" to get 0.857375, or %85.7375.
