Summary
Continuous random variables are a type of random variable that can take any value within a range. Students get practice in identifying and working with these variables.
Probability density functions
A probability density function is what a continuous random variable has. This part asks students to identify correct statements about these functions and other related functions.
Mutually exclusive events
Mutually exclusive events are a pair of events that cannot both happen. This part asks students to identify correct statements about these events and other related events.
Continuous random variables
Continuous random variables can be represented by certain things. This part asks students to identify what these things are.
The normal distribution
The normal distribution is a type of continuous probability distribution. This part asks students to identify correct statements about this distribution.
Key terms
- Continuous random variable
