Now pretend you are tossing a coin 7 times, and take X to be the total number of tails that come up. There are then 27 = 128 possible outcomes: TTTTTTT, HTTTTTT, THTTTTT, TTHTTTT, TTTHTTT, TTTTHTT, TTTTTHT, TTTTTTH, HHHHHHT, HHHHHTH, HHHHTHH, HHHTHHH, HHTHHHH, HTHHHHH, THH, HH. Take X to be the total number of tails that come up. The possible values of X are Check Clear Do it Separate the values with commas. Now fill in the missing probabilities. The other missing probabilities will appear when you correctly answer the question (or press P(X= 0 1 2 3 4 5 6 7 "Do it")
