In the binomial experiment, the number of times the six-sided cube was rolled is the number of trials. Thus the number of trials for this binomial experiment is 12. The formular for a binomial experiment is nCx (p)^x (q)^(n - x) where: n is the number of trials, x is the success event, p is the probability of success, q is the probability of failure.
