Acoin is tossed three times, with 'heads' or 'tails' recorded after each toss. the number of possible outcomes for this experiment is

6 possible out comes for each coin toss (3) he has the probability to throw heads or tails (2) so to outcomes per 3 coin toss is 6 out comes

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
