The money raised from a raffle with a $200 prize where the tickets cost $2.50 per person.
a)
Continuous; the money raised depends on the number of tickets sold, and since any number of tickets can be sold, this situation is continuous.
b)
Discrete; the money raised depends on the number of tickets sold, and since only a whole number of tickets can be sold, this situation is discrete.
