Question:medium
In a chess tournament, assume that your probability of winning a game is 0.3 against level 1 players, 0.4 against level 2 players and 0.5 against level 3 players. If among the players 50% are level 1, 25% are level 2 and the remaining are level 3, the probability of winning a game against a randomly chosen player is
