Barbara claims that her horse can do simple addition problems. she showed her horse 8 different cards with simple addition problems, and the horse was able to tap his foot to indicate whether the answer was correct or incorrect. the horse correctly identified all 8 cards. eric didn't believe barbara's horse could do addition, so he set up a trial to test whether the horse was just guessing. he flipped 8 coins to see how many would land tails up. he did this 53 times, and the results are shown in the dot plot below: a dot plot with values of 1, 2 3, 4, 5, 6, 7, 8 corresponding to frequencies of 3, 5, 8, 11, 8, 7, 5, and 1 respectively. based on these results, can barbara's horse add? yes, the chances of getting 8 correct by guessing are very low no, the chances of getting 8 correct by guessing are very low yes, it is likely to get them all correct no, horses can't add
