Hypergeometric geometric
Suppose (22 Jolly ranchers total) and 5 out of which are blue,
Now random Jolly ranchers divide evenly into two segments
So, (n = 22/2 = 11)
P(one obtains all 5 blue Jolly ranchers) = ?
Now,
K = 5
r = 5
N = 22
n = 11(divided 22 Jolly ranchers evenly into two segments )
P(X = 5) = 5C5 x 17C2 / 22C11
P(X = 5) = 0.00019278 rounded to 0.0002
Given that,
There are 22 jolly ranches and of which 5 are blue.
Randomly jolly ranchers are divided evenly into two segments.
The pmf hypergeometric distribution is as follows.
is population size
is the number of successes in the population
is the sample size
is the number of successes in the sample
The combination is as follows.
