With the help of np.negative_binomial() method, we can get the array of negative binomial series by using np.negative_binomial() method.

Syntax : np.negative_binomial(n, p, size) Return : Return an array of negative binomial series.

Example #1 : In this example we can see that by using np.negative_binomial() method, we are able to get an array of negative binomial series by using this method. Python3 1=1

# import numpy
import numpy as np

# using np.negative_binomial() method
gfg = np.random.negative_binomial(3, 0.33, 10)

print(gfg)

Output :

[ 8 12 23 1 2 7 5 3 1 5]

Example #2 : Python3 1=1

# import numpy
import numpy as np

# using np.negative_binomial() method
gfg = np.random.negative_binomial(5, 0.1234, 50)

print(gfg)

Output :

[15 26 60 19 15 18 15 55 46 36 28 50 13 47 40 56 24 80 47 19 36 62 45 57 37 32 15 28 20 65 40 34 34 35 28 38 43 50 20 71 33 40 31 50 25 29 46 38 32 86]
