Binomial distribution (a) Calculate the probability Pn(n) that n spins are up out of a total of N for N = 4 and N = 16 and put your results in a table. Calculate the mean values of n and nusing your tabulated values of Pn(n) It is possible to do the calculation for general p and g, but choose p = q = 1/2 for simplicity. Although it is better to first do the calculation of PN(n) by hand, you can use Program Binomial.
