Answer:

33%

Explanation:

2 blue marbles + 2 green marbles = 4 marbles

1st draw for blue: 2/4 (2 blue marbles out of 4 marbles)

2nd draw for green: 2/3 (1 less marble from 4, marble not put back in)

2/4 x 2/3 = 4/12 = 1/3 = 0.33 or 33%

Answer: your answer should be 50%

Step-by-step explanation: This is because there are only four marbles in the bag total and only 2 are blue and only 2 are green so your chances of pulling out either is 50%
