Hello guys! I am looking for the acceptible methods to calculate probability chances "1 x 2" on football matches. I read a lot of articles, but there are no useful information that can help me. I started to investigate probability theory myself and I freezed after some calculations.
Let imagine we have match between Chelsea and Liverpool. I understand how calculate probabilitly for each team. I took last ten Chelsea's home matches and last ten Liverpool's away matches. After simple calculations(win/10; draw/10; lose/10) I received:
P(Chelsea win at home) = 0,55;
P(Chelsea draw at home)=0,35;
P(Chelsea lose at home) = 0,10;

P(Liverpool win away) = 0,20;
P(Liverpool draw away)=0,55;
P(Liverpool lose away) = 0,25;

But I could now understand how to use this calculated data to predict match Chelsea - Liverpool. I tries to apply sum and multiplication theorems, but there could be incredible result, for exmaple over 1. I definetly understand that this calculation would be very approximatly and that there are a lot of parameters that affect on football result, but I think that it could be useful to predict match. Thank you for any help!
