## What is An Introduction to Artificial Intelligence?

An Introduction to Artificial Intelligence by **IIT Delhi** course introduces the variety of concepts in the field of artificial intelligence. It discusses the philosophy of AI, and how to model a new problem as an AI problem. It describes a variety of models such as search, logic, Bayes nets, and MDPs, which can be used to model a new problem. It also teaches many first algorithms to solve each formulation. The course prepares a student to take a variety of focused, advanced courses in various subfields of AI.

## CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of the average of best 8 assignments out of the total 12 assignments given in the course.

Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

**YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF THE AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.**

## NPTEL An Introduction to Artificial Intelligence Assignment 8 Answers 2022:-

**Q1.** Mona is really excited for her birthday and she makes a large number of her signature muffins. The muffins can either be choco-chip or blueberry and both are equal in number. Bennet receives a pack of 20 muffins which have been randomly sampled from Mona’s kitchen. Given that at least 18 of the muffins Bennet has received are blueberry, let the probability that all the muffins Bennet received are blueberry is p/q where p and q are co-prime.

What is p+q?
