Question

Marli has one bag of different colored, same-size chips. there are 4 blue chips, 5 red chips, and 3 black chips. what is the probability that she will pull a blue chip and without replacement pull another blue chip?

Answer 1

Hi there!

There are 12 total chips. The probability that she will pull a blue chip is 4/12, or 1/3. Without replacing the chip, there are now 11 chips total. The probability that she will pull a blue chip now, is 3/11. Then, we can multiply the two fractions together to find the probability that she will pull a blue chip and without replacement, pull another blue chip. The probability is 3/33, or 1/11.

Hope this helps!! :)
