medium📝 Debug Q14 of 15
Step-by-Step Solution
Solution:
Step 1: Check the poisson object creation
poisson(4) creates a frozen distribution with mean 4. The parameter can be passed positionally.Step 2: Verify pmf method usage
Calling pmf(3) on the frozen distribution is correct and prints the probability of 3 events.Final Answer:
No error, code runs correctly -> Option CQuick Check:
Frozen distribution with positional mu works = A [OK]
Quick Trick: Frozen distribution accepts positional mu parameter [OK]
Common Mistakes:
MISTAKES- Thinking mu must be named explicitly
- Assuming pmf is not a method of frozen distribution
- Believing import is incorrect without error
