A marble is drawn at random from the bag shown below. The bag contains 3 green, 4 yellow, 5 blue, and 8 pink marbles.

The probability of the person to draw a blue or green marble is 2/5.

Step-by-step explanation:

In order to solve this, you need to know how many blue and green marbles are together. So in this case, 3 green marbles plus 5 blue marbles equals 8 green or blue marbles. You then have to know the total amount of marbles for all colors. So, 3+4+5+8=20 marbles. You then put the fraction as 8/20. This is representing that there are only 8 marbles out of 20 marbles. So then after you find the fraction, you simplify the fraction to 2/5.

Therefore, your answer is 2/5.
