see this is the formula to obtain how many times do you need to extrac a binary ball so it appears 1111 and you do till it appears so its undefined

you guess it from the expected succes of a martingale betting system vs the expected loses which is 1/2, every time the other option appears, you win every time it appears your option in a four row when you win 16 minus the one you bet

so the formula to obtain how many times you have to play to obtain 1111 is:

((2^4)-1)/x=1/2

so 1111 will appear every 30 times while 0101 every 16

its got to be this way or you could win in a casino but who knows maybe theres a way to win

what i wonder is if someone designed a game thinking that in a bingo with repeated numbers there the same chance to get number ten than eleven which would be badly bdaly flwaed and would allow for 25% edges in your favour
