He concludes that the probability of a head for this coin is , =0.30 Answer parts a and b 6 elow a. Your friend claims that the coin is not balanced, since the probability is not 0.50 What's wrong with your friend's claim? O A. Environmental conditions such as temperature and humidity can cause the results of flipping a balanced coin to be skewed and thus appear unbalanced O B. Probability doesn't prove anything about the coin because probability is subjective. C. In the short run, the proportion of a given outcome can fluctuate a lot. A long run of observations is needed to accurately calculate the probability of flipping heads O D. A coin is balanced as long as the probability of each outcome is closer to 0.5 than it is to 1 or 0 b. If the probability of flipping a head is actually , what would you have to do to ensure that the cumulative proportion of heads falls very close to , O A. Flip the coin in a vacuum so it is unaffected by environmental conditions. O B. This cannot be ensured because probability relies on subjective information O C. Flip the coin many times to obtain a long run of observations 8 K/s OK'S O Time Remaining: 01:09:05 Next 1:36 O 9 3 27C $50125 062, 2021/10/1 Intel ORE GEFORCE RTX
