So we are playing a game, first we toss 2 coins, if we get:
2 consecutive heads (HHH, HHT, THH) when we win,
1 head then we lose
2 non-consecutive head (HTH) then we advance to the next game
Next game: rolling 2 dices, we win if we get the difference between 2 dices is exactly 1.
I'm trying to calculate the winning rate for this game.
My approch is to use conditional probability: I make A as an event when it's HTH, B as an event when the difference of 2 dices is 1. I have the probability when winning the second games after losing the first game is :
Pr[B|A] = Pr[B union A] / Pr[A]
how do I add it up to the probability when I win by having 2 consecutive heads? Do I add them or multiply them together?
