Question

Determine whether the events are independent or dependent. hoose the correct reasoning

school raffle is held for prizes after a dance. Each winning ticket put back into the drawing once picked.
Not enough information is provided. The number of tickets per student is needed.
These events are neither independent nor dependent since some students might have more raffle tickets than others.
The events are independent. One drawing has no effect on the next drawing.
The drawings are dependent, since after winning, a student has a smaller chance of winning again.

Answer 1

These events are independent

Explanation:

When the first ticket is drawn, all students have the same chance of getting chosen.

When choosing the second ticket, the previous ticket is put back, making it so that all students have the same probability of getting picked.

Since both probabilities are equal, this is an independent event.
