Gambling at a slot machine is an example of which reinforcement schedule?

When one gambles using a slot machine, the reinforcement schedule is what we call the variable-ratio shedule. In the operant conditioning process, schedules of reinforcement play a central role. When the frequency with which a behavior is reinforced, it can help determine how quickly a response is learned as well as how strong the response might be. Defined as a schedule of reinforcement where a response is reinforced after an unpredictable number of responses, variable-ratio also creates a steady, high rate of responding. Two of the good examples of a reward based on a variable-ration schedule are gambling and lottery games.
