A football team's best player plays for the full game in 50% of matches, part of the game in 40% and takes no part in the other 10%. When he plays for the full game the probability of a win for his team is 0.7; when he plays for part of the game it is 0.5; when he doesn't play it is 0.3.

Draw a tree diagram for this data.

How woudl you go about doing this? I'm really confused with what the braches are. I assume the first 2 would be win and lose but I don't know what next.
