Kelley to draw a marble without looking,
record the color, and then return the marble
to the bag. Kelley repeats the trial 20 times,
recording 8 blue and 12 red marbles. Based
on these results, predict how many marbles

Step-by-step explanation:

Carl asks  Kelley to draw a marble without looking, record the color, and then return the marble  to the bag. Kelley repeats the trial 20 times,

The number of blue marbles = 8

The number of red marbles = 12

The probability of blue marbles in the bag = = 40%

The probability of red marbles in the bag = = 60%

Since the total number of marbles is 100,

The number of blue marbles = 40% = 40.

The number of red mabrles = 60% = 60.
