[Solved] Identify the error in this code snippet: from scipy.stats import binom n, p = 5, 0.4 prob = binom.pmf(n, 3, p) print(prob) | SciPy

SciPy - Statistical Functions (scipy.stats) Basics

Identify the error in this code snippet:

from scipy.stats import binom
n, p = 5, 0.4
prob = binom.pmf(n, 3, p)
print(prob)

Apmf function does not exist in scipy.stats.binom

BParameters n and k are swapped in pmf call

CImport statement is incorrect

DProbability p is out of range

Step-by-Step Solution

Solution:

Step 1: Check parameter order in binom.pmf
The correct order is pmf(k, n, p), but code uses pmf(n, 3, p), swapping n and k.
Step 2: Identify the error
Swapping n and k causes wrong calculation or error.
Final Answer:
Parameters n and k are swapped in pmf call -> Option B
Quick Check:
pmf(k, n, p) order must be correct [OK]

Quick Trick: pmf(k, n, p) order is fixed; swapping causes errors [OK]
