Deriving the binomial theorem formula From everything weve seen so far we can establish the following true statements about the raw expanded form without any simplification of any binomial of the form. Binomial Distribution Formula is used to calculate probability of getting x successes in the n trials of the binomial experiment which are independent and the probability is derived by combination between number of the trials and number of successes represented by nCx is multiplied by probability of the success raised to power of number of successes represented by px which is further multiplied by probability of the failure raised to power of difference between number of success and number.
