Yes, independent.
Explanation of Solution
Given:
Two fair roll having one red face sided and other is green face sided.
Concept used:
Definition condition
Calculation:
Probability is the number of favourable outcomes divided by the number of possible outcomes.
Thus, Definition condition probability:
Since, the red die need to be a 3 for the sum to be 7 (knowing that green die shows at 4).
Since, the possible combinations to make 7 are
These probabilities should be identical if the events “
Thus, they are independent.
