And then the last condition is the probability of success in this context success is a heads on each trial each trial is constant. If doing this by hand apply the binomial probability formula. If so apply the binomial formula as many times as needed and add up the results.
The binomial distribution formula can also be written in the form of n-Bernoulli trials where n C x nxn-x.
The mean value of the binomial distribution is EX m np The variance of the binomial distribution is VX s 2 npq. Fixed number of trials. If we apply this formula to. This formula is commonly referred to as the Binomial Probability Formula.
