A bag contains 150 marbles which are red, green, and blue. Suppose a student randomly selects a marble without looking, records the color, and then places the marble back in the bag. The student has recorded 9 red marbles, 15 green marbles and 6 blue marbles. Predict how many blue marbles are in the bag.

Respuesta :

Ok so the total number of marbles is 150
And these can be either red, green or blue
If they’re are 9 RM, 15GM and 6 BM then the total number of marbles the student picked was 30M
So 150/30 is 5
So 6 * 5 is 30 so the total number of BM is 30
:)

The number of blue marbles that I would predict that would be in the bag is 30.

How many blue marbles are in the bag?

In order to determine the number of blue marbles that are in the bag, the ratio of blue marbles picked to the total number of marbles picked should be multiplied by the number of marbles in the bag.

Number of blue marbles = (6/30) x 150 = 30 marbles
