Betty claims that her dog can do simple addition problems. She showed her dog 8 different cards with simple addition problems, and the dog was able to tap his paw to indicate whether the answer was correct or incorrect. The dog correctly identified all 8 cards. John didn't believe Betty's dog could do addition, so he set up a trial to test whether the dog was just guessing. He flipped 8 coins to see how many would land tails up. He did this 30 times, and the results are shown in the dot plot below:

I don't understand how the dot plot is supposed to determine anything.

anonymous · Answer

thats the same exact problem i had, i tried looking at it but i just still cant understand it.

Well, the coin has nothing to do with it. Unless he means if the dog is doing it randomly like the coin. I guess they want you to use the coin to show the probability of the dog guessing all of them correctly. Which would mean there is a probability of 0/30 because there is none where all eight landed tails up. So I am guessing the dog wasn't guessing. Hope it helps! :3
