what are the statisitcal chances of all 3 lanes or 2 lanes losing in every placement match.

i swear ive been playing nothing but jungle and lanes that i gank or dont gank end up losing. all 10 matches i havent had a single lane that did well enoguht to be considered winning. (pi played one mid match) example: 1st game. im rengar i gank top. give my riven two kills. gank mid get a kill. by 15th minute malphite is legendary.
