Question 10 • Mathematics II

Which scenario depicts two independent events?

Answer
A
Luka paints during school and he stains his shirt.
B
The school play opens tonight and it is raining.
C
Ari chooses a partner for a group project and then Ezekial chooses a partner from the remaining classmates.
D
Neva is hungry and she buys a snack from the concession stand.

Explanation

Independent events are events where the occurrence of one does not affect the probability of the other. Whether it rains does not affect whether the school play opens tonight, so these events are independent. The other scenarios describe events that are connected or affect one another.
