Question 1
What is the formula for Conditional Probability?
- P(A|B) = P(A ∩ B) / P(B)
- P(A|B) = P(B) / P(A)
- P(A|B) = P(A) + P(B)
💡 Hint: Remember to consider what the condition is referring to.
Question 2
True or False: If A and B are independent, then P(A|B) equals P(A).
- True
- False
💡 Hint: Think about what independence means.

Question 1
In a factory, 70% of the time a machine operates without errors. Consider a scenario where 90% of the errors are due to programming issues (P(E|P) = 0.9) and 10% are mechanical (P(E|M) = 0.1). If a machine fails, what is the probability that it was due to programming issues?
💡 Hint: Break down the error probabilities into parts and apply.
Question 2
Two fair coins are flipped. What is the condition probability that at least one coin is heads, given that one of them is known to be heads?
💡 Hint: Draw out the sample space considering the conditions.
