According to my research on different scientific terminology, I can say that based on the information provided within the question This is an example of contingency existing between putting money in the machine and getting pop out. Contingency is defined as a a future event or circumstance which is possible but cannot be predicted with certainty. Which is exactly what is happening in this situation since the most likely scenario would be that the machine drops a can of pop after putting money in, but still it cannot be predicted with certainty because the can may get stuck or the machine may break.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
