C. Ari chooses a partner for a group project and then Ezekiel chooses a partner from the remaining classmates.
D. Luka paints during school and he stains his shirt.
The correct answer and explanation is:
Correct Answer: A. The school play opens tonight and it is raining.
Explanation (300 words):
To determine which scenario depicts two independent events, we need to understand what independent events are.
Independent events are events where the outcome of one event does not affect the outcome of the other. In other words, whether one happens has no impact on whether the other occurs.
Let’s analyze each option:
A. The school play opens tonight and it is raining.
- These are two completely separate events: the opening of the school play and the weather.
- The weather (rain) has no bearing on whether the play will open (assuming it’s not an outdoor event).
- These events are independent.
✅ Correct Answer
B. Neva is hungry and she buys a snack from the concession stand.
- Neva’s hunger directly influences her decision to buy a snack.
- Her being hungry increases the likelihood of her buying food.
- These events are dependent.
C. Ari chooses a partner for a group project and then Ezekiel chooses a partner from the remaining classmates.
- Ari’s choice affects who is left for Ezekiel to choose from.
- Ezekiel’s options change based on Ari’s decision.
- These events are dependent.
D. Luka paints during school and he stains his shirt.
- The act of painting increases the chance of a shirt stain.
- Staining is a direct consequence of painting.
- These events are dependent.
Summary:
Only Option A describes two events that are completely unrelated — the weather and a scheduled event at school. Because neither affects the other, they are independent events, making A the correct answer.
