    P(4) = 1/6 so the probability of a 4 three times P(4, 4, 4) = 1/6 x 1/6 x 1/6 =1/216

    ok i will explain better out of 6 numbers one is a 4so one spin to land on 4 would be a 1/6 (one out of six chance) then you get two spins which means the 6 numbers get doubled so now you have a one out of 12 chance to hit four again but you want three spins in a row to land on four so you add another six which now makes your chances of spinning a 4 three times in a row one in 18 or 1/18

    actually it is right... each spin is independent of the next. draw a tree diagram to represent each spin|dw:1336077609050:dw|

    well good luck snow... as that solution is incorrect... but its your choice... well countonme... what are the possible outcomes in the sample space... can you list them

    another explanation: a probability of an event = (nº of positive posibilities)/(nº of all posibilities) nº of all posibilities is 6^3=216 nº of wanted outcomes = 1 (is the 4,4,4) so the probability is 1/216
