I am trying to calculate the probability that any a number events will occur. For instance you have 5 events that a 75% chance of happing how do you calculate the probability that any of the five will occur (be true)?
In my case I have a list of universities I want to apply to; given their acceptance rates I'd like to find my chance of success/failure. But I'll spare you the details. I really ought to know the math behind this. However I have found most explanations of this utterly unhelpful.
