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

Answer from: smartgirl30

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

Step-by-step 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%.
