Question

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 .

Answer 1

The percent will likely decrease with more trials

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%
