Answer:
<u><em>fixed-ratio</em></u><em>; </em><u><em>variable-ratio
</em></u>
Explanation:
The fixed ratio is a reinforcement method. <em>Reinforcement is given in this method after a number of responses have been completed. </em>
<em>The number of responses expected continues to be constant.</em>

<em>Betting and casino activities are great examples of a payout dependent on a schedule for a variable ratio.</em>
