Question

PLZZ HELPPP!!!To get out of jail free in the board game MONOPOLY, you have to roll doubles with a pair of standard dice. If you fail in three attempts, you have to pay a fine to get out of jail. Determine the probability of getting out of jail without paying a fine.

Answer 1

look at a dice chart like this

how many cases do doubles show up?

A "double" is where you roll the same number at the same time (eg: rolling two '6's)

Answer 2

6/36

Answer 3

which reduces to 1/6. Agreed?

Answer 4

Yes

Answer 5

The probability of rolling doubles is 1/6

What is the probability of not rolling doubles?

Answer 6

30/36 - 5/6

Answer 7

1 - (1/6) = 6/6 - 1/6 = 5/6

I think that's what you mean to say?

Answer 8

yea

Answer 9

the probability of not rolling doubles is 5/6

multiply that with itself 3 times to get (5/6)*(5/6)*(5/6) = ???

Answer 10

125/216

Answer 11

that is the probability of rolling 3 non-doubles

it is the probability of having to pay the fine

Answer 12

subtract 125/216 from 1 to get the final answer

Answer 13

1 - (125/216) = ???

Answer 14

OMG i got it thanks alot so it would be 91/216

Answer 15

right?

Answer 16

91/216 is correct

Answer 17

okay thanks alott!!

Answer 18

you're welcome

Answer 19
