I was working on to simulate a problem of probability "Suppose there is a test containing 180 questions. What is the probability of getting all answers wrong(Test is multiple choice test each question containing 4 choices)(Also consider the fact that the test taker is just guessing)".I tried simulating this problem by using the random module but there is a problem. Most of the time the correct answers would be much larger than the wrong answers. I wanted it to be entirely random including a possibility that the test taker has 100 questions wrong and just 80 questions right. Is it the problem with my code or is it the problem with random module ? (as random module is a pseudo random number generator). import random j=int(input("Enter simulations: ")) n=int(input("Enter no of questions: ")) def event(n): L=[] for i in range(n): s=['C','W','W','W'] random.shuffle(s) L.append(s) return L def choose(events,n): l=[] m=[] for i in events: l.append(random.choices(i,k=1)) for k in l: for s in k: m.append(s) return m def check(p): correct=0 wrong=0 for h in p: if h=='W': correct+=1 else: wrong+=1 return correct,wrong answers=0 for ghf in range(j): p=choose(event(n),n) corrects,wrongs=check(p) print("Correct answers",corrects,"\n","Wrong answers",wrongs) print() if wrongs==10: answers+=1 print('Accuracy',(answers/j)*100) (Sorry I am new to stackoverflow and only know a bit of basics of python) Continue reading...
