Using the formal definition of independence, determine whether events A and B are independent or dependent.
Flip three coins, with
Event A: The first two coins are heads.
Event B: There are at least two heads among the three coins.
The table below shows the sample space and the favorable outcomes for each event:
Since p(A) × p(B) ≠ p(A and B), the events are dependent. Catch you on the flip side.
