6.2 BINOMIAL PROBABILITIES

 Features  Fixed number of trials (n)  Trials are independent and repeated under identical conditions  Each trial has only two outcomes: success (S) or failure (F)  For each trial, the probability of success is the same  Probability of success (p)  Probability of failure (q)  p + q = 1 and q = 1 – p  The central problem → find the probability of r successes out of n trials **Example 3 p.217/Guided Exercise 4 p.218 BINOMIAL (BERNOULLI) EXPERIMENTS
