Here is a question asked in a job interview at Qualcomm Inc.

An unfair coin with P(H) = 0.3 = 1-P(T) is tossed 10 times. Find the probability of getting even numbers of heads.

Electrical engineering majors are encouraged to try.

" Well. Zero is not even or odd number. It is very debatable. So i didn't included in the equation. Some people say it as even, some say it as an odd number."


I am still not satisfied. Tell me who are these "some" who say 0 is odd. You claimed this at the beginning. Now, if you are to back it up, give me the facts. Else, admit you made a mistake and apologize for misleading the Sajha visitors!!! :) (unless you are going to name ram, shyam, harke etc...)

Bibas. Well many people don't admit it as even number. So with first look only other alternative is the odd number.  That's what used to be believed by very few people a history book of 0 " a natural history of zero". However, with time experts started to keep0 in even number and many experts kept  0 in neither odd nor even.  Do you know there are still many tribes which don't have number 0.

Whatever i wrote in that sentence was just plainly to make my point that I believe it is not an even number . Yeah I could have better said that some people may believe. I

If you go back before that the question that 3 X posted and I solved I believe 0 not as an even number. And I still haven't received any answer from 3 X about what is the right answer.

Again the same thing. Now, who are these "many people?" Initially it was "some" and now it is "many"
hehe...When you say many, it has to be more than 1, right? How many examples did you give? You can find zero being used as even in many textbooks and journals alike. When you go against the convention, you have to back it up...with some real good evidences.
 lol...after all this , you are expecting that people will consider your answer right? Do you think most people think the way you think? hehe.....just add the probability of 0 as well. That will solve your problem.


PS: I don't believe 2+2=4 This is bull****. I strongly believe 2+2=5. Am I wrong? hehe, it is about convention kid. We created the system of numbers. It was not there for us to just grab it. You can call  the "evens" as odds and vice versa. You can consider infinity to be a number and zero to be infinity. lol...its just that the landscape changes and we will have a different system, but we will prevail. So, learn to appreciate the importance of convention in mathematics.

bibas there is no point arguing with you. With people who may believe  i can't name tom, dick and harry. I have already told you to read a book called " a natural history of zero". This is the one of the reference book in our masters. If you want to you are free to read.

Regarding, zero not being an even number i have presented my points. I have also shown you have making zero as even present several mathematical complication. 

Secondly, I dont see any point arguing with you. You seem to pick a point and get stuck rather than trying to understand the whole idea put forwarded by me.  When i said " people may  believe zero as even or odd " meant that you are free to chose zero as per your convention because it will hold good in any event. I said this in regards to justify my answer of not chosing probablity of zero in the question of 3X. But if your idea is to irritate me then i should better not discuss with you.

Tell me when did i said zero as an infinity. Mate you seriously need some math tuition. I can continuely nag by copying same sentence you typed to me.

We had very intelligent question about probablity going on until you came and start to interrupt.
