Calculation:
Event A represent sum of outcomes which are greater than 2 but less than 9, and event B represent sum of outcomes which are greater than 5 and less than 9.
Two events A and B are independent if and only if the probability that both events occur is the product of the probabilities of the event. Symbolically,
Use the
Substitute the values in rule (1). Since,
Conclude the events are not independent.
