Rosita is pulling marbles from a bag there 14 green and 6 orange marbles. She randomly pulls a marble reccords the color, and returns the marble to the bag. After doing 10 trails, she finds that she drew an orange marble 50 % of the time.

what kind of comparision can be made?

The percent will likely decrease with more trials, or, The percent will likely stay the same with more trails, or, The percent will likely stay the increase with more trials.

The percent will likely decrease with more trials

Step-by-step explanation:

The theoretical probability for orange marbles is

P (orange) = orange/total = 6 / (6+14) = 6/20 = 3/10 = 30%

The more times the experiment is done, the closer we should come to the theoretical probability. Eventually we should come closer to 30%
