Calculate Probability of Coin Flips and Conditional Events
Probability Warm-Up
This exercise assesses fundamental understanding of probability concepts through two distinct problems:
- Coin Flips: You are to determine the probability of obtaining exactly two heads when a fair coin is flipped three times.
- Conditional Probability: Given two events, A and B, with the following probabilities: P(A) = 0.3, P(B) = 0.4, and the probability of both A and B occurring, P(A ∩ B) = 0.12. Compute the conditional probability of A given B, denoted as P(A | B).

Core dilemma
Assessing the candidate's foundational quantitative reasoning and their ability to articulate basic statistical principles with clarity and precision, even when the problem itself is simple. The true test is not just the answer, but the rigor and depth of explanation.
