Question 1

What is a Binomial Distribution:

Answer 1

is a discrete probability that calculates the likelihood of of getting a specific # of success in a fixed number of independent trials. where each trial has only 2 outcomes (success or failure) and the probability of success remains the same across trials.

Question 2

What is a Bernoulli Trial?

Answer 2

is when a random experiment results in one of two mutually separate outcomes. (Independent)

Question 3

Describe the Bernoulli process:

Answer 3

a sequence of Barnoulli trails in which:
1. each trial has only two outcomes. Success and Failure
2. The probability of success remains the same from trial to trial
3. the trials are independent of each other. The outcome of one trial does not affect the other.

Mean:
Probability of Success:
Probability of Failure:
Variance:
