Let's Review
- ____ is the measure of the likelihood that an event will occur.
- Probability is quantified as a number between ____ and ____.
- There are two types of probability, namely ____ and ____ probability.
- Theoretical probability = Number of favorable outcomes / Total number of ____.
- Experimental probability = Number of favorable outcomes / Total number of ____.
- The collection of all possible results is called the ____ ____ of the experiment.
- The ____ ____ of the sample space is formed by considering all different collections of possible results.
- The probability of an event A is written as ____ , ____ , or ____ .
- If two events A and B occur on a single performance of an experiment, this is called the ____ or ____ ____ of A and B, denoted as
- If two events, A and B are independent then the ____ probability is for example, if two coins are flipped the chance of both being heads is.
- If two events are mutually exclusive then the probability of ____ occurring is denoted as .
- If two events are mutually exclusive then the probability of ____ occurring is denoted as . For example, the chance of rolling a 1 or 2 on a six-sided die is
Answer
- Probability is the measure of the likelihood that an event will occur.
- Probability is quantified as a number between 0 and 1.
- There are two types of probability, namely Theoretical and Experimental probability.
- Theoretical probability = Number of favorable outcomes / Total number of outcomes.
- Experimental probability = Number of favorable outcomes / Total number of trials.
- The collection of all possible results is called the sample space of the experiment.
- The power set of the sample space is formed by considering all different collections of possible results.
- The probability of an event A is written as , , or .
- If two events A and B occur on a single performance of an experiment, this is called the intersection or joint probability of A and B, denoted as
- If two events, A and B are independent then the joint probability is for example, if two coins are flipped the chance of both being heads is.
- If two events are mutually exclusive then the probability of both occurring is denoted as . .
- If two events are mutually exclusive then the probability of either occurring is denoted as . For example, the chance of rolling a 1 or 2 on a six-sided die is
