Question

Edgar has a bag of 10 marbles (3 green, 5 blue, and 2 red). If he picks one marble out of the bag at random, what’s the probability that he will get a blue marble? Explain how you determined that probability.

Answer 1

There are 5 blue marbles and 10 total marbles.

The probability of picking blue is the number of blue marbles/ total marbles.

Probability = 5/10 which reduces to 1/2

The answer is 1/2
