Here is a Python function to determine probability distribution of data

import numpy as np

def probability_distribution(data):
    """ I determine probability distribution of data """
    data = np.array(data)
    data = data.astype(float)
    data = data / np.sum(data)
    return data

# Enter the matrix
matrix = np.array([[1,2,3],[4,5,6],[7,8,9]])

# Calling the function
print((probability_distribution(matrix)))

#Example Output

# [[0.02222222 0.04444444 0.06666667]
#  [0.08888889 0.11111111 0.13333333]
#  [0.15555556 0.17777778 0.2       ]]
