# binomial theorem and its simple applications pdf

In a binomial distribution the probabilities of interest are those of receiving a certain number of successes, r, in n independent trials each having only two possible outcomes and the same probability, p, of success. Hence, (0.99) 5 = (1-0.01) 5. When an exponent is 0, we get 1: (a+b) 0 = 1. A rod at rest in system S' has a length L' in S'. However, the binomial theorem is still rather crude and it is failed to carry out much more complicated discussions. The binomial theorem is not only useful in algebra but also has important applications in many other subjects, such as combinatorics, permutations and probability theory. This theorem was first established by Sir Isaac Newton.

These are associated with a mnemonic called Pascal's Triangle and a powerful result called the Binomial Theorem, which makes it simple to compute powers of binomials. set are called the elements, or members, of the set. One more important point to note from here, is the sum of the binomial coefficients can be easily calculated just by replacing the variables to 1. It is often useful to de ne n k = 0 if either k<0 or k>n. Later we will also give a more general de nition for the binomial coe cients.
