 
 <prompt> The vending machine fails to drop a snack when it’s purchased one in six times. One in ten times, it will accidentally drop two snacks. The rest of the time, it drops the purchased snack. If thirty people have used the vending machine once each to purchase a snack, how many snacks has the vending machine dropped? <response>: ```Máquina ti o ṣe iṣẹ 30 tó ṣe pe o kò le fi ẹran rẹ 30 / 6 = 5 wọn.
Máquina ti o fi ẹran 2 30 / 10 = 3 wọn.
