WebMay 31, 2024 · To answer this question, we can use the following formula in Excel: 1 – BINOM.DIST (3, 5, 0.5, TRUE) The probability that the coin lands on heads more than 3 times is 0.1875. Note: In this example, BINOM.DIST (3, 5, 0.5, TRUE) returns the probability that the coin lands on heads 3 times or fewer. So, to find the probability that the coin ... WebThe binomial theorem formula is used in the expansion of any power of a binomial in the form of a series. The binomial theorem formula is (a+b) n = ∑ n r=0 n C r a n-r b r, where n is a positive integer and a, b are real numbers, and 0 < r ≤ n.This formula helps to expand the binomial expressions such as (x + a) 10, (2x + 5) 3, (x - (1/x)) 4, and so on. The …
