##### Scenario Online assessment covering core probability concepts. ##### Question If you flip a fair coin three times, what is the probability of exactly two heads? Given two events A and B with P (A)=0.3, P (B)=0.4, P(A∩B)=0.12, what is P(A|B)? ##### Hints Recall binomial distribution and conditional-probability formula P(A|B)=P(A∩B)/P (B).

This question evaluates foundational probability skills, including reasoning about outcomes of discrete random experiments (coin flips) and conditional probability, and is relevant for Data Scientist roles in the Statistics & Math domain.

Problems

Coin flips: You flip a fair coin three times. What is the probability of getting exactly two heads?
Conditional probability: Given events A and B with P(A) = 0.3, P(B) = 0.4, and P(A ∩ B) = 0.12, compute P(A | B).
