Practice Questions 1. Find the coefficient of the term in the binomial expansion of the following expression: . 2. Find the coefficient of the term in the binomial expansion of the expression: . 3. Can the Binomial Theorem be used to expand an expression of the form 1/(1-x) ...
‘a’ of each term is a positive integer and the value depends on ‘n’ and ‘b’. for example, for n=4, the expansion (x + y) 4 can be expressed as (x + y) 4 = x 4 + 4x 3 y + 6x 2 y 2 + 4xy 3 + y 4 the coefficients of the binomials in this ...
The total number of a particular outcome (such as ‘head’ in coin tossing) in n trials can be 0, 1, 2,…, n, and the probability (prob(i)) of having i particular outcomes is given by nCipiqn−i. Because this is the ith term of the binomial expansion of (p + q)n, this ...
