Question

A bag contains blue, red, and green marbles. Paola draws a

marble from the bag, records its color, and puts the mar-
ble back into the bag. Then, she repeats the process. The
table shows the results of her experiment.
Color
Blue
Red
Green
Number of
Times Drawn
14
30
6
Based on the results, which is the best prediction of how many times
Paola will draw a red or blue marble in 500 trials?

Answer 1

500 × P(blue marble) = 500 × 14/50 = 140

500 × P(red marble) = 500 × 30/50 = 300

Based on the results, the best number of predictions Paola will draw a red marble or a blue marble is 440 times in 500 trials.
