comment on : It's hard to believe your statistics!! (HIV STATISTICS)
Apr 25, 2007
If the probability of being infected in a single exposure is p = 1/1000, the probability of being infected in n exposures is given by the binomial: P(n) = 1 - (1-p)^n in our case, if n where 1000, the probability of being infected in 1000 exposures is aprox 63% ( P(1000) = 0.6323) Having sex 3 times a week aprox, means that more than 1/2 of the magnetic couples were become infected before 6 years, only having vaginal unprotected sex. Statistics aplyies only to a great number of people or a great number of exposures. ** hugs ** and sory about my english.
Response from Dr. Frascino
Your English is quite understandable. It's statistics that tend to confuse folks! I absolutely agree statistics apply to large numbers of people.
