Two events are described as independent. What does that mean?
AOne always follows the other
BOne does not affect the other
COne rules the other one out
DOne is more likely than other
Answer & Solution
Correct answer: B. One does not affect the other
1. Independence is about influence, not about timing.
2. Two events are independent when the outcome of the first does not change the chances for the second.
3. Flipping a coin twice is the standard example, since the first result changes nothing.
4. Drawing sweets from a box without replacing them is dependent, since the choices shrink.
