Binomial problems: Advanced

**MathGuru**, Thursday, May 27, 2010 at 2:06pmThe easiest way to do this problem is to use a binomial probability table. If you do this, you will need to find P(3), P(4), P(5), and P(6). In the table, n = 6, p = .14, x = 3, 4, 5, 6 (for each one). Add all these probabilities together for the total probability.

I hope this will help.
