Re: Is this cool with you?That is where I am getting those problems from 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #1702 20130414 13:47:27
Re: Is this cool with you?I wonder if bobbym has a devious variation of the last problem he will be posting soon.

Re: Is this cool with you?Nothing devious ever entered my mind. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #1704 20130414 15:01:58
Re: Is this cool with you?I would call many of the problems you pose devious. The 9's problem is pretty devious if you ask me...

Re: Is this cool with you?The only problems doctors can cause you are money problems. I suggest you visit him. Or at least go and get a massage.

Re: Is this cool with you?He will not explain or point me to the book, title and author. I am sure it is stated better there. In mathematics, you don't understand things. You just get used to them.

Re: Is this cool with you?
This can also be done using linearity of expectation.

Re: Is this cool with you?Well, let me see please. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #1722 20130417 18:33:32
Re: Is this cool with you?Well, I just give each car a random variable which is 1 if the car is painted and 0 if not. Its expected value is E[Xi]=1(135/800)^23. The expected number of painted cars is E[X1+X2+...+X800], which, based od linearity of expected value, equals E[X1]+E[X2]+...+E[X800]=800*(1(135/800)^23), which gives the correct answer.
