    That bit of info was sneakily concealed by using the word otherwise - that's my story anyway 😉

    But would it have been 33.3% if that hadn't have been the case?

    Vaknso gets an extra toss; if he gets tails, he's at a disadvantage because he now has to get more heads than Rhymester to win; if he gets heads, he's at an advantage because (over the remaining 9 tosses each) Rhymester has to get more heads than him to win.
    Guys,

    I think I have fairly simple explanation for it:

    Every toss has probability 50%.
    It does not matter how many time they toss the coin. the only condition is the total number of them must be odd.
    You will find the answer more easy if you forget who tosses for how many times. It does not matter. One player can do it all and it makes no difference, because:
    HEAD = I win
    TAILS = you win

    So, if they tos once, each has 50% to win. 3x times, because again each has 50% in every turn etc etc.

    😛

    ok, how about if Vaknso tosses the coin 90 times and Rhymester 81? 😛

    In that case, the probabilities are...

    Vaknso Wins = 54.4%, or 4059/7462
    Rhymester Wins = 44.5%, or 3321/7462
    Draw = 1.1%, or 82/7462

    Did you use a spreadsheet or something to give you the answer? 😠
