probability1) A man is given n keys, in random order of which only one will unlock his door. He tries them one by one (without replacement). find P(man succeeds on k*th trial) #2 20100915 06:35:12
Re: probabilityHi Sam; A question for you, you have posted several other questions. I don't know whether or not you needed help or you were just posing a problem. I answered them, can you check them and tell me what you think? 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. #3 20101212 14:00:48
Re: probabilityuna clase consta de 14 hombres y de 30 mujeres de los cuales la mitad de los hombres y la mitad de las mujeres usan anteojos. Hallar la probabilidad de que una persona escogida al azar 1) sea hombre 2) use anteojos 3) sea hombre y use anteojos. #4 20101212 14:03:31

Re: probabilityHi noemi1982;
Welcome to the forum! I do not understand what you mean by the method of Laplace. 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. #6 20101212 14:43:53
Re: probabilityregla de Laplace: se aplica cuando los "n" resultados son equiprobables. #7 20101212 14:49:53
