Summary
Probability and statistics are branches of mathematics. This document helps students understand and practice key concepts in these fields.
Binomial distribution
A binomial distribution is a discrete probability distribution. It describes the number of successes in a fixed number of independent Bernoulli trials with the same probability of success.
Normal distribution
A normal distribution is a continuous probability distribution. It is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Probability rules
Probabilities must be assigned to sample space outcomes. The probability assigned to each sample space outcome must be between 0 and 1, inclusive.
Mutually exclusive events
Two events are mutually exclusive if they cannot occur at the same time. A student is asked to determine whether two given events are mutually exclusive.
Key terms
- Binomial distribution
- A discrete probability distribution describing the number of successes in a fixed number of trials.
- Normal distribution
- A continuous probability distribution that is symmetric about the mean.
- Z value
- The number of standard deviations that a value is from the mean.
- Standard normal distribution
- A normal distribution with a mean of zero and a standard deviation of one.
- Mutually exclusive events
- Events that cannot occur at the same time.
- Continuous random variable
- A random variable that can take any value in a given interval.
Questions this document helps with
- When is a distribution binomial?
- What does a negative z value indicate?
