How many red balls in jar (Negative Hypergeometric Distribution)
$begingroup$
We have 100 balls in a jar. We take samples without replacement. How many of them have to be red so that we will have found one red ball after at most 16 tries with a probability of P>0.5 for k repeating experiments?
I have been advised to use the negative hypergeometric distribution. I can understand how it works but i am stuck at some point.
For the Negative hypergeometric distribution there is:
N=100
K=C, Population of successes- red balls
F=100-C, Population of Failures
How can we calculate this? The result can be decimal.
