Ron randomly pulls a pen out of a box that contains 1 red, 2 black, and 3 blue pens. He does this 4 times, replacing the pen each time, but pulls out a blue pen only 1 time. Ron concludes that the observed frequency of pulling a blue pen will eventually be closer to the expected frequency based on the theoretical probability of pulling a blue pen. Which reasoning best supports his conclusion? The experimental probability of pulling a blue pen based on the observed frequency will get closer to as the number of trials increases. The experimental probability of pulling a blue pen based on the observed frequency will get closer to as the number of trials increases. The theoretical probability of pulling a blue pen based on the expected frequency will get closer to 17 as the number of trials increases. The theoretical probability of pulling a blue pen based on the expected frequency will get closer to as the number of trials increases.
