## snowballhockey 3 years ago What is the probabiltiy that you will spin a spinner numbered 1-6 and get a 4 three times in a row??

1. countonme123

1/6 for one time 1/12 for two 1/18 for three

I am confused Help

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

5. snowballhockey

That is so not right

6. countonme123

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|

Two confuseing cambell thanks other kid

9. countonme123

i try to make things simple no prob

10. campbell_st

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

11. countonme123

im sorry but i dont know what you are talking about

12. myko

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

14. campbell_st

lol.... what are you 18 outcomes... to get 1/18

15. countonme123

lol right
