Let's say you make three bets... first one has 30% chance of winning, second has 40%, and last has 50%. What are the odds that you win at least two of them? How is that calculated?
So far I know that I can't just add them together. I can't multiply them together. I tried manually doing each pair (.3*.4 , .4*.5, .3*.5) to calculate the odds of those pairs both winning... but I'm not sure how to add them together.
