Question

Michelle has a bag with marbles in it. Some of the marbles are blue, some are green, and some are yellow. She draws one marble at random, records the color, and returns it to the bag.

Here is her data after 500 trials:
blue: 120
green:119
yellow:261

She wants to know the probability of drawing a blue marble from the bag. Which of these probabilities is most likely?

Answer 1

24% (0.24)

Explanation:

Using the data from her 500 trials, we can predict the probability of her drawing a blue marble from the bag by dividing the number of times she drew a blue marble (120) by the total of trials she performed (500).

120 ÷ 500 = 0.24

0.24 = 24%
