Answer 1

Answer: 10/25 is the probability of choosing a blue marble.

Explanation:

First, find out how many marbles there are in total. 3 + 10 + 8 + 4 = 25

Then, each number of marbles is how many out of 25. So, for example, red would be 3/25. Blue - 10/25. Green - 8/25. Yellow - 4/25

It asks you what the probability is, so, find the blue fraction that is out of 25, and thats the probability.

blue probability - 10/25

green - 8/25

yellow - 4/25

red - 3/25
