5-2 Binomial Probability Distributions

Question 1

What are the rules of binomial probability distribution?

Answer 1

1. The procedure has a fixed number of trials 2. Trials must be independent 3. Each trial has only 2 outcomes 4. The probability of success remains the same in all trials

Question 2

List the relevant notation for binomial probability distribution:

Answer 2

n = the fixed number of trials

p = the probability of a successful outcome in a single trial

q = the probability of a failing outcome in a single trial

x = the number of successes that occur in the n trials

P(x) = Probability of getting “x” successes
