There are 10 brown, 10 black, 10 green, and 10 gold marbles in bag. A student pulled a marble, recorded the color, and placed the marble back in the bag. The table below lists the frequency of each color pulled during the experiment after 40 trials..
Outcome Frequency
Brown 13
Black 9
Green 7
Gold 11
Compare the theoretical probability and experimental probability of pulling a green marble from the bag.
A The theoretical probability, P(green), is 50%, and the experimental probability is 11.5%.
B The theoretical probability, P(green), is 25%, and the experimental probability is 25%.
C The theoretical probability, P(green), is 25%, and the experimental probability is 17.5%.
D The theoretical probability, P(green), is 50%, and the experimental probability is 7.0%.
