Question

What is the probability of choosing a blue marble out of a bag containing 3 red , 1 green , 4 blue , and 2 yellow marbles.

Answer 1

the probability of choosing a blue marble is 4/10 or 0.4 or 40%.

Explanation:

the first thing you do is count all the marbles together which in this problem its 10. then you read what the question is asking you in this case 4 blue, so you make it a fraction 4/10.to make it a decimal, you divide 4 ÷ 10 it will give you 0.4, and to make it a percent you you multiply 4×10, it will give you 40%.

Answer 2

2/5 because you add up all the number the total is your bottom part of the fraction, and the number of blue is the stop you should get 4/10 then simplify to 2/5
