Question

the question is to simulate the result of tossing n die and generate a probability graph based on your simulation in python3

the result is supposed to be normal distribution, but mine isn't. i would like to know what's wrong in my code.

def roll_and_add_dice(num_dice, num_trials = 10**6): outcomes = [] sum_of_die = 0 for j in range(num_trials): for i in range(num_dice): sum_of_die += randint(1,7) outcomes.append(sum_of_die) sum_of_die = 0 return outcomes # Your code here show_distribution (roll_and_add_dice(2), title='Probability Distribution for Sum of Two Dice') Probability Distribution for Sum of Two Dice 0.16 Probability

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

Hi the code you provided is working absolutely fine. What I think is there is some error in hist type.

Below is my code to this problem

import random
import matplotlib.pyplot as plt
def roll_and_add_dice(num_dice,num_trials=10**4):
n=num_trials;
nd=num_dice;
out=[];
S=0;
for j in range(n):
for i in range(nd):
S=S+random.randint(1,7);
out.append(S);
S=0;
return out;
  
out=roll_and_add_dice(2);
plt.hist(out,density=True);
plt.show();
