How to use the binomial probability formula
WebI wrote below code to use binomial distribution CDF (by using scipy.stats.binom.cdf) to estimate the probability of having NO MORE THAN k heads out of 100 tosses, where k = 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. and then I tried to plot it using hist (). WebUsing the probability mass function for a binomial random variable, the calculation is then relatively straightforward: P ( X = 3) = ( 15 3) ( 0.20) 3 ( 0.80) 12 = 0.25 That is, there is a 25% chance, in sampling 15 random Americans, that we would find exactly 3 that had no health insurance.
