Please check attache problem.png We have a game colled BattleShips.... one user hide only one ship on board 10x10 = 100 field and second user have X shots to find where user one hide ship and we want to give them 50% equal chance to win or lose... and we want to ask you how many shots(how many field he can check) we need to set up for user to 50% chance to win or lose. User have 4 size ships option and we want to calculate how much maximum shots can take one user to find where another user hide ship: a) 1 field ship on board 10x10 = 50 shots yes? it will be 50% chance... 100 field and 50 shots b) 2 field ship on board 10x10 = How many? c) 3 field ship on board 10x10 = How many? d) 4 field ship on board 10x10 = How many? The most important thing is also calculate how much maximum shot can take user to avoid sytuation when he can shot field in smart way to be 100% sure that he win every game... For example with 4 field ship you can shot to all field in column 4 and 8 and all field shot to verse D and G and you are 100% sure that you will hit the 4 field ship... We need to avoid that kind situation in all a), b), c) and d) option.

Pick one ship and drag him on board 1 2 3 4 5 6 7 8 9 10 reward 0,223 x2 reward 0,223 x2 reward 0,223 x3 reward 0,223 Ready
