Should be simple enough... unfortunately I'm 20 years removed from college and can't seem to find an equation so I thought I'd post it here.(adsbygoogle = window.adsbygoogle || []).push({});

If there is a 30% chance that Bob will give me a $1, and a 30% chance that Ted will give me a $1 and a 30% chance that Frank will give me a $1. What are the chances that at least one of them gives me a $1?

Very hypothetical, but if someone could give me the equation to solve it then I can figure some other problems out on my own.

Thanks,

Dale
