Yeah, tx. I got the same thing but in a very long (and confusing) way.
In the end n > 1.74 i.e. n = 2
Tx a lot. But is there a simple way of seeing if its a binomial distribution or not? I thought I know but clearly I don't. Or can the same answer be reached if I use binomial distribution...
(I'm really losing it, been at it for 10hrs.)
Qn=0.45n ;
Rejecting 1 is: Q1=0.451; Which implies accepting n-1, which is = 1-0.451 = 0.55
Q2=0.452; accept n-2 = 1-0.452 = 0.798; etc.
So if x = minimum nr of articles to be submitted, then I'm actually trying to find
Accept n-x = 1-0.45x...
Homework Statement
The rejection rate of a certain journal is 45%. If the journal accepts articles at random, what is the minimum number of articles someone has to submit to have a probability of more than 0.75 of getting at least one article accepted?
Homework Equations
I'm almost sure...
