Q2.1: You have a bag of 12 marbles, 6 are red, 4 are white, and 2 are blue. You randomly pick three marbles from the bag. What is the probability of drawing 1 red, 1 white, and 1 blue (in this order)? The theoretical result is 2/55 -3.636%. Write a simulation of 100,000 trials to verify the answer Hint. You can follow the steps here: 1. Create an array of 12 elements, bag = np.array(lr,r, rrrrww.w w,b', b']) 2. Create the desired outcome of 3 marbels of red, white, and blue, bag3 = np array(l'r' w b'l) 3. For each of the trial, you use np.random permutation() to shuffle the bag array 4. Create a Boolean array by comparing the first three elements of the shuffled array with the desired outcome 5. If the values the Boolean array are all True -> you have a match

Python: numpy def serial_numbers(num_players):"""QUESTION 2- You are going to assign each player a serial number in the game.- In order to make the players feel that the game is very popular with a large player base,you don't want the serial numbers to be consecutive. - Instead, the serial numbers of the players must be equally spaced, starting from 1 and going all the way up to 100 (inclusive).- Given the number of players in the system, return a 1D numpy array of the serial numbers for the players.- THIS MUST BE DONE IN ONE LINEArgs:num_players (int)Returns:np.array>> serial_numbers(10)array([1. 12. 23. 34. 45. 56. 67. 78. 89. 100.])>> serial_numbers(12)array([1. 10. 19. 28. 37. 46. 55. 64. 73. 82. 91. 100.])""" # print(serial_numbers(10)) # print(serial_numbers(12))
