Binomial Distribution 1

This is just for practice.  This is not for a grade.  You can take it as many times as you want or none at all.

1-p=q (also 100%-p%=q%)

(_nC_x)(p^x)(q^n-x)

Just plug in the numbers to their respective variables in the formula

n=fixed number of trials (n is always bigger than x)

C=Combination 

x=specific number of successes in n trials (x is always smaller than n)

p=probability of success in one of n trials

q=probability of failure in one of n trials
