Solution:

Given that:
P (Failing in Paper 1) = 0.3
P (Failing in Paper 2) = 0.2
P (Failing in Paper 1 | Failing in Paper 2) = 0.6

To find:
P (Failing in both papers)

Explanation:

Using Bayes' theorem, we can calculate the probability of failing in both papers.

P (Failing in Paper 1 and Paper 2) = P (Failing in Paper 1 | Failing in Paper 2) * P (Failing in Paper 2)
= 0.6 * 0.2
= 0.12

Therefore, the probability of a student failing in both the papers is 0.12.

Answer: Option C (0.12)

Given that someone or all in class Failed in Paper2, now the prob. of failing in paper 1. Its like how much all failed in paper 1 when its already told how much in ppr 2. Probably of failed in both paper / when paper 2 failed probability already selected. In the area of failed in paper 2 how much failed in paper 1. I hope you can understand the inner meaning.
