The sum of the probabilities in a binomial distribution must equal 1. To show that this is TRUE, we first take q = 1- p so that q + p = 1. Below is a table showing a binomial distribution with n = 1 observation, and its sum is 1. What will the probability distribution be if n = 2, and the probability of success is p?
—————— —— Number of successes Chance 0 q 1 p —————— ——
A:
—————— ——— Number of successes Chance 0 q 1 q - p 2 p —————— ———
B:
—————— —— Number of successes Chance 0 q 1 qp 2 p —————— ——
C:
—————— —— Number of successes Chance 0 q 1 p 2 p —————— ——
D:
—————— ———– Number of successes Chance 0 q 1 p 2 1- q- p —————— ———–
