    Probability at least 1 is chosen?
    the question I have is...

    there are:

    21 yellow jelly beans
    30 green jelly beans
    36 red jelly beans
    87 total jelly beans

    what is the probability that at least 1 is yellow?

    I don't know what to do here. I tried doing 1-p(not yellow) but its not giving me the right answer.

    any help would be great!

    You did not state how many are being drawn. With replacement or without replacement?
