Slot machines reward gamblers with money according to which reinforcement schedule?

variable interval

fixed interval

Explanation:

A fixed interval scheme refers to a reinforcement scheme in which an activity is rewarded only when a certain period of time is over. In the fixed interval scheme, there is a large amount of activity always occurring simultaneously at the end of a time interval. This kind of scam is very common in games, especially slot machines that reward gamblers with cash.
