  1. First, you would need to add 33+25 because you need to find the total number of marbles that are in the bag.

    algebraic expression: 33+25=x

    x=58

    Next you would need to take the amount of blue marbles and make a fraction over the total amount. The fraction is 25/58. Therefore, the probability of selecting a blue marble is 25/38
