    probability - roll a 6-sided die 8 times
    1. You roll a fair 6-sided die 8 times. What is the probability that you will roll at least four “4’s”?

    Look up "probability of dice rolling" on Google. We don't do homework for you.

    Hint:the probability of rolling "at least four 4's" is the same as rolling exactly four 4's, or five 4's, or six fours, or seven fours, or eight 4's. It's also equal to 1 minus the probability of rolling zero 4's, or one 4, or two 4's, or three 4's - which is slightly easier to calculate.
