A bag contains a total of 150 green and blue marbles. Without looking, a student chooses a marble, records the color, and places it back in the bag. The student records 4 green marbles and 11 blue marbles. Which is the best prediction of the total number of blue marbles in the bag? (1 point)

Question

what’s the answer

Answer 1

The best prediction of the total number of blue marbles in the bag would be 110 blue marbles since the student took out a total of 15 marbles (4 green and 11 blue), and the remaining marbles in the bag would be 150-15=135 marbles. Since the student recorded 4 green marbles, the remaining marbles must be blue, so the best prediction of the total number of blue marbles in the bag would be 135-4=110 blue marbles.
