In a certain online computer game, there are 55 players on the Green Team and 100 players total in the game.The game randomly chooses a player to receive a bonus. Let the event A and the event B be as follows.A: The player the game chooses is on the Green Team.B: The player the game chooses is not on the Green Team.Find the following probabilities.

Solution
The probability of an event is calculated by dividing the number of ways the event can occur by the total number of outcomes.
Event A: The player the game chooses is on the Green Team. The number of ways this can occur is 55 (the number of players on the Green Team). The total number of outcomes is 100 (the total number of players in the game). So, the probability of event A, P(A), is 55/100 = 0.55.
Event B: The player the game chooses is not on the Green Team. The number of ways this can occur is 100 - 55 = 45 (the number of players not on the Green Team). The total number of outcomes is still 100. So, the probability of event B, P(B), is 45/100 = 0.45.
