1 AnswerSoftware1 decade agocardinality of infinite sets (i couldnt really think what to call it...)?
ok so i understand that as there exists a mapping from ℕ to ℚ they have the same cardinality but so far every example i have seen doesn't preserve the order of the rationals ( i believe that this would be impossible) is there a word for when there is a one to one function that does preserve order
the function f:ℕ->ℕ ; f(x)=2x which lists the even positives, so that f(1)<f(2)<f(3)<.... is an example of what i mean
sorry for the poor explanation hopefully you understood what i was getting at
1 AnswerMathematics1 decade agodifficult function help?
Let f : X → Y and g : Y → Z be functions.
(i) Write down the denition of the image of f and the composition g ∘ f.
(ii) What constraint must be imposed on X and the image of g in order for f ∘ g
to also be well-dened? State the domain and co-domain of f ∘ g.
need help answering part two please show all details
in case im wrong here is what i believe part one to be
i believe the answer to part one is that the image of f is the set of value {f(x)|x∈X} i.e all the values that f(x) can take given the domain X.
and that the composition function is g ∘ f : X → Z such that g ∘ f(x)=g(f(x))

1 AnswerMathematics1 decade agopoker question plz read (reguarding rules)?
ok heres the situation
this is a torny not a cash game
player one hand 99
player 2 hand ak
pre flop the pot is raised by player 1
player 2 pushes and it is folded round to player 1
player 1 takes a second to consider but player 2 mistakenly believes that he has been folded too and shows his ak
player two says 'well that makes my decision easyer' and throws his chips into the middle
he also says something bout how player 1 has mucked his hand i cant remember exactly
the dealer then asks if player 1 is happy to continue
player1 clearly says no but the dealer deals the flop anyway giving ak a straight (qj10)
he then continues to deal the turn and river ak holds up
this would of knocked player 1 out but he argues that he wasnt happy and player 2 had mucked
after a solid 10 mins of argueing the torny organiser steps in but as she hadnt witnesses the event and were getting slightly conflicting stories she desides to split it up as if the hand nvr happened
my question is ment to happen in this situation did player 2 really muck or as his hand was never mixed in with other cards was it still live also is it even possible to muck when your all in in torny play?
