    Questions about WeBWorK #7. (I decided to start creating new discussion threads for each assignment, as the old “Questions” thread was getting a little long)

    There have been a few questions about problem #2 — here’s a tip:
    The key phrase in the problem is “at most 2 of them” (NOTE: your version may say “at most 3” or some other number). “At most 2” means we need to consider not just the situation in which x = 2, but all values for which x is at MOST 2. Which other values of x do we need to consider? You will need to use the binomial formula once for each of these x’s, and add up the resulting probabilities. If you’re still stuck, leave a reply here.
