Explanation: When we solve for probability, we want to find out how many of something there is out of its total. So in this case, we want to see how many white balls there are out of the totals balls in the box. We already know that there are 10 white balls, so we need to figure out the total balls in the box, by adding up. 8 green balls + 16 red balls + 10 white balls + 6 pink balls = 40 balls in total. Now we know that the fraction would be 10/40, as there are 10 white balls out of 40 total balls. Finally, we simplify the fraction to 1/4, therefore the answer is B.
You find probability of drawing the marble by doing specific marble/total marbles. To find total marbles, add all the marbles: 8 + 16 + 10 + 6 = 40 Since we are searching for the probability of drawing the white marble and there are 10 white marbles,: 10/40 simplifies to 1/4 so b!
