right so the second result isn't affected by the first result right? You could pick another 85. I'm just trying to understand how they know that the chance of picking an 85 year old is .008 like how do they know that? Am I thinking too hard about this?
Homework Statement
The probability that a person picked at random is 85 years old is 0.008 . if two people are picked at random find the probability of that:
a. they are both 85
b. neither is 85
c. at least one is 85
I have two questions like this one and I am so confused as to how you...
I read on NPR that the pilot had 40 years of experience so he definitely wasn't a n00b!
He also made sure to walk the length of the plane twice to make sure that no one was still on it before he exited. He even has a cool name "sully"... sounds like something from Miami Vice. LOL
Hello physics forum! This is my first post here. I am currently enrolled in a biostats class and I don't know how this forum feels about offering help when someone is stuck, but I will probably be in that position soon! lol
So are there any biostatisticians around? Hopefully I won't need to...
