Shea bought 10 tickets for the raffle for free homecoming entry but she did not win. Months later she also buys 10 tickets for the senior prom raffle, hoping this will be the time she wins. Which schedule of reinforcement is best used to explain this scenario?

A. FRB. VRC. FID. VIE. C

B - Variable ratio

Explanation:

In operant conditioning, a variable-ratio schedule is a schedule of reinforcement where a response is reinforced after an unpredictable number of responses. This schedule creates a steady, high rate of responding.

Shea is purchasing the tickets despite losing the other time, which conforms with the reinforcement and rate of response.

Gambling and lottery games are good examples of a reward based on a variable ratio schedule.
