Question

A box has 3 pencils, 5 pens, and 4 markers. What is the probability of randomly pulling out a marker, then after putting it back your friend

grabbing something that is not a pencil?

Answer 1

If I remember correctly, possibility is favorable outcome / total possible outcomes.

Explanation:

So this means:

Favorable outcomes: 3 (Pencils)

Total possible outcomes: 12 (3 + 5 + 4)

3 / 12 = 0.25

Hope it helps!

Answer 2

1/4 chance of pulling a pencil then 3/4 for ur frend
