Re: Math puzzle: Breaking the camel\'s back.
[ QUOTE ]
With probability 1/2 , the camel's back will be broken first on the second straw . You may argue that the probability x2 <x1 is 1/2 and so the probability 1< x1+x2 <1+x1 is 1/2 .

Let me clarify this part . x2 may either belong to the interval [0,x1] or [x1,x2] and either choice is equally likely . The probability x2 belongs to [0,x1] is 1/2 , or equivalently , the probability x2 belongs to [1,1+x1] is 1/2 .
