Question 1054111: Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to find the probability of x successes given the probability p of success on a single trial.
n=8, x=6, p=0.55

it is 8C6 (0.55)^5*0.45^2
form n choose x * p^x*(1-p)^n-x
x and n-x add to n.
8C6 is 8!/6!2!=8*7/2=28
multiply that by the other two terms and get 0.1569
