Best ResponseYou've already chosen the best response.0fav no. of outcomes =4096, I ran a c++ program for that, in case anyone would like to view it ?

Best ResponseYou've already chosen the best response.0am not too sure with the sample space.

Best ResponseYou've already chosen the best response.1i am not sure but one version of the sample space is just all possible \(6^6\) outcomes when you roll six dice

Best ResponseYou've already chosen the best response.0yep that was my first attempt, which leads us to 64/729 i.e. ans = 793 , but it tells me the ans is wrong. Sample space should be something else, as we are allowed to arrange.

Best ResponseYou've already chosen the best response.1well not really, the sample space is usually defined to be "the set of all possible outcomes" but not necessarily the denominator of your probability

Best ResponseYou've already chosen the best response.1the fact that you cannot distinguish between (a,b,c,d,e,f) from (a,d,b,e,c,f) does not make them the same outcome

Best ResponseYou've already chosen the best response.1but should shut up because i have read your problem now 6 or 7 times and i do not understand it. it seems like the probability would depend on k

Best ResponseYou've already chosen the best response.1i would have no idea how to do this

Best ResponseYou've already chosen the best response.0hmm please tell me if I am understanding the problem correctly myself : we throw 6 dice 1st no. should not be div by 3 sum of 1st 2 should also not be div by 3 sum of 1st 3.. . . 6

Best ResponseYou've already chosen the best response.1evidently you have to exclude any 3 and any 6, but after that i cannot imagine how you proceed

Best ResponseYou've already chosen the best response.1yeah what you said is what i think it is

Best ResponseYou've already chosen the best response.1so for example the ordering on the left in the example does not work, but the ordering on the right does, so that one would be considered a success

Best ResponseYou've already chosen the best response.2Hint: Let x be sum of outcomes of all 6 die then, Look for case x Mod 3=1 And case x Mod 3 = 2 only..... This will simplify the problem

Best ResponseYou've already chosen the best response.2when x Mod 3=1 then, out of the six numbers, u can pick 3 numbers such that their sum is "a" where "a "mod 3 =0 and the rest three numbers sum is b where b mod 3=1

Best ResponseYou've already chosen the best response.2Now, Let p=1Mod3=4Mod3=1 , q=2Mod3=5Mod3=2 , r=3Mod3=6Mod6=0 So, to pick three numbers such their sum is divisible by 3, r,r,r r,p,q p,p,p q,q,q to pick three numbers such that their is b where b mod 3=1, r,r,p r,q,q p,p,q
