Question 613628: The probabilities that 2 band students show up for practice are .6 and .8. Find the probability that at least one does not show up for band practice.
[On this one, I can figure the probability that both show up, which is .92=(.6+.8)-(.6*.8), but I cannot seem to figure out if at least one does not show up. Your detailed explination is greatly appreciated!]
