Question

At a high school movie night, the refreshments stand sells popcorn and soft drinks. Of the 100 students who came to the movie, 62 bought popcorn and 47 bought a drink. 38 students bought both popcorn and a drink.
Are buying a drink and buying popcorn independent or dependent events? Justify your answer.

Answer 1

Independent events. Someone does not have to buy popcorn to buy a drink and someone does not have to buy a drink to buy popcorn.

Answer 2

Answer: Buying a drink and buying popcorn are independent events.

Step-by-step explanation:

Independent events are referred to as events whose occurrence does not affect the occurrence of another event.

In the case of this question, 62 bought popcorn while 47 bought a drink.

This means that the buying of popcorn by a student does not mean buying of a drink. It does not affect each other.

I hope this helps.
