That's 2. Let me get the calculator out just so we don't make any mistakes here. So this is going to be the calculator out. So on average, if we have 110 liters and it's going to be drunk by 50 men, including ourselves, I guess, that means that it's the problem. So we would run out if on average more than 2.2 liters is used per man. So this is the same thing as the probability of the average, or maybe we should say the sample mean, or let me write it this way, that the average water use per man of our 50 men is greater than, or we could say greater than or equal to, let me say greater than, well, I'll say greater than, because if we write on the money, then we won't run out of water, is greater than 2.2 liters per man. So let's think about this.
