Question

you want to measure traffic on ca-283 n/wildwood ave bridge during the late evening. with a correct probability distribution the following are either discrete random variable or continuous random variables. select all the discrete random variables (there may be more than one). the number of cars that use the bridge in one hour. the total number of cars that cross the bridge. the time each car crosses the bridge. the time between each car crossing the bridge.

Explanation:

Step1: Define discrete and continuous variables

Discrete variables have countable values. Continuous variables can take any value in an interval.

Step2: Analyze "The number of cars that use the bridge in one hour"

The number of cars is countable, so it is a discrete random - variable.

Step3: Analyze "The total number of cars that cross the bridge"

The total number of cars is countable, so it is a discrete random - variable.

Step4: Analyze "The time each car crosses the bridge"

Time can take any value within a range (e.g., 10.5 seconds), so it is a continuous random - variable.

Step5: Analyze "The time between each car crossing the bridge"

Time can take any value within a range (e.g., 5.2 seconds), so it is a continuous random - variable.

Answer:

The number of cars that use the bridge in one hour, The total number of cars that cross the bridge
