I'm trying to put together an app for fun that has a scenario where I need to figure out a probability equation for the following scenario:

Suppose I have a number of attempts at something and each attempt has a success rate (known ahead of time). What are the odds after doing all those attempts that a success happens?

For example there are three attempts (all will be taken individually).

**The first is known to have a 60% success rate. The second is known to have a 30% success rate. The third is known to have a 75% success rate. What are the odds of a success occurring if all three attempts are made?**

I've tried several formulas and can't pinpoint the correct one.

Thanks for the help!
