Multiplying ten binomials, however, takes long enough that you may end up quitting short of the halfway point. Now, notice the exponents of a. k! The Binomial Expansion. The main use of the binomial expansion formula is to find the power of a binomial without actually multiplying the binominal by itself many times. For instance, the binomial coefficients for ( a + b) 5 are 1, 5, 10, 10, 5, and 1 in that order. If the probability of success on an individual trial is p , then the binomial probability is n C x p x ( 1 p) n x . Now we have to clear, this coefficient, whatever we put here that we can use the binomial theorem to figure (Try the Sigma Calculator). (a+b)^4 = a^4 + 4*a^3*b + 6*a^2*b^2 + 4*a*b^3 + b^4 ( 1 vote) Show more. When you come back see if you can work out (a+b)5 yourself. ( n k)! How to do a Binomial Expansion TI 84 Series Calculator.
