Lesson 1372 of 1524
Discrete Random Variables
The probability p of a success is the same for any trial (so the probability q = 1 - p of a failure is the same for any trial)
Practice this chapterThe probability p of a success is the same for any trial (so the probability q = 1 - p of a failure is the same for any trial) The n trials are independent and are repeated using identical conditions
There are one or more Bernoulli trials with all failures except the last one, which is a success There are only two possible outcomes called success and failure for each trial
Bernoulli trials — an experiment with the following characteristics: There are only two possible outcomes called success and failure for each trial The probability p of a success is the same for…. probability p of a success — the same for any trial (so the probability q = 1 - p of a failure is the same for any trial). n trials — independent and are repeated using identical conditions. binomial experiment — a statistical experiment that satisfies the following three conditions: There are a fixed number of trials, n There are only two possible outcomes, called success and, failure ….

What does “Bernoulli trials” mean in Discrete Random Variables?
- 1Use the wording this chapter gives for Bernoulli trials.
- 2The book says: an experiment with the following characteristics: There are only two possible outcomes called success and failure for each trial The probability p of a success is the same for….
- 3Do not use the meaning of probability p of a success. That term means the same for any trial (so the probability q = 1 - p of a failure is the same for any trial).
Result: an experiment with the following characteristics: There are only two possible outcomes called success and failure for each trial The probability p of a success is the same for…
Why. That is the meaning this chapter gives for Bernoulli trials.
Do not swap Bernoulli trials and probability p of a success. Bernoulli trials means an experiment with the following characteristics: There are only two possible outcomes called success and failure for each trial The probability p of a success is the same for…. probability p of a success means the same for any trial (so the probability q = 1 - p of a failure is the same for any trial).
