A gambler simulates 20 plays of a card game, wins 1 time, and estimates P(winning) = 1/20 = 0.05 He then simulates 5,000 plays of the game, wins 450 times, and estimates P(winning) = 450/5,000 = 0.09 Which estimate, 0.05 or 0.09 is probably closer to the true theoretical probability and why? A. 0.05 because it's a smaller number B. 0.09 because the Law of Large Numbers says that the larger the number trials, the better the estimate of the probability C. 0.05 because the Law of Small Numbers says that the smaller the number trials, the better the estimate of the probability D. Both are equally close
