And I am saying that you need to take a statistics class, because you are way off on that.Originally posted by DrMetallica
'Tis nothing about how you went wrong, I am simple stating that assuming you took it perfectly, assuming you are not lieing, and assuming the effectiveness rate is 99.99%, the probability that someone would get pregnant 4 times is .000000000000000001.
Let's say that the odds of someone having a heart attack in their twenties is 1 in 5000. Now, let's say that Jim has a heart attack when he is 22 years old because he has a heart condition. He is that one guy out of 5000. Now... what are the odds that he will have another heart attack while he's in his twenties? Would you say that his odds are still 1 in 5000? By your model, Jim's odds of having a second heart attack are 1 out of 25,000,000. Jim should feel lucky that he had a heart attack at 22, because that means that his odds of having a second heart attack in his twenties have dropped considerably. Of course, that's stupid. Jim's odds of having a second heart attack in his twenties are markedly greater than the average person in their twenties.
Same situation here.
