    No replacement.

    540 numbers plus 10 crosses in a hat = 550

    If I chose a random sample of 42 out of the 550, what is the probability I would choose 6 crosses?

    Pretty damn hard.

    Thanks. I can do with some help.

    Sorry, just saw your answer. I'm not sure what you mean by replacement?
