Probability to happen

[iNeedHelpWithThis]

There are 3 player: Player 1, Player 2 and player 3. The only thing they can do is TO DRINK or NOT TO DRINK water. Player 1 start. Player 1 drink water every time. Player 2 drink water only 10% of the times player 1 drink water. Player 3 drink water only 20% of the times player 1 drink water. What is the probability that after player 1 drink water, at least one of player 2 and player 3 to drink water as well. What's the solving of this kind of problem? What are the steps?

Is it known whether players 2 and 3 decide independently whether to drink?

What do you know about P(A or B)?

What do you know about P(A or B)?

Player 3 doesn't care about player 2, and player 2 doesn't care about player 3, they care just in relation between player 1-2 and player 1-3

I asked what you know about P(A or B); evidently, the answer is nothing (or that you don't recognize the connection to your problem). Check it out here:

For example, if player 1 always drinks water, then what is the exact probabilities that player 2 and player 3 will drink water.
