Which of these is an example of continuous random variable a. number of flights leaving an airport b. distance of a javelin throw c. pieces of mail in your mailbox d. attendance at a sporting event

The correct answer would be Choice B. Distance of a javelin throw.

For example, the distance for a javelin throw could be 6.70819203 feet.
However, you would not say that you have 6.70819203 flights, pieces of mail or people at a sporting event.

A= b/2 because u simplying both sides of equation
