alleryStart learning →Two events are independent when the outcome of the first:
AAlways doubles the second's odds
BDoes not change the second's probability
CGuarantees the second will occur
DPrevents the second from occurring
Answer & Solution
Correct answer: B. Does not change the second's probability
1. Independence is about information rather than about timing.
2. Rolling a die twice is the standard example.
3. The outcome of the first roll does not change the probability for the outcome of the second roll.
4. If two events are not independent, then we say that they are dependent events.
