Question

Rachel has 4 different colored folders and 3 different colored notebooks. She is late for school and quickly grabs a folder and notebook without paying attention to their color. What is the probability Rachel will pick the green folder and then pick the purple notebook? Reduce if necessary.

Answer 1

Answer:

1/12.

Step-by-step explanation:

Prob ( first picking the green  folder) = 1/4.

Prob ( first picking the purple notebook) = 1/3.

Required probability = 1/4 * 1/3 = 1/12.

Note: The probabilities are multiplied because the 2 events are independent.
