Homework Statement
A die is based so that the numbers 5 & 6 appear 3 times more often than the numbers 2 , 3 & 4. Calculate;
i)The probability that a two is thrown.
ii)The probability that two consecutive throws are > or equal to 10.
The Attempt at a Solution
Well I wasn't sure how to go about this so i imagined all of the outcomes;
5 5 5 6 6 6 2 3 4 , satisfies the criteria meaning a 2 would be 1/9, however i have a feeling that that's nonsense...:S
Then for ii) Combo's are 46 64 65 56 55 66 so (4 * 1/9) + (2 * (3/81) = (36/81+6/81) = (42/81)?
I don't know how to go about these questions, sorry for bugging everyone >.<
