Suppose two dice (one red, one green) are rolled. Consider the following events. A: the red die shows 1; B: the numbers add to 4; C: at least one of the numbers is 3; and D: the numbers do not add to 9. Express the given event in symbolic form. HINT [See Example 5.]Either the numbers add to 9 or the red die shows a 1.D ∩ BD ∩ A D' ∪ AD' ∩ AD' ∪ BHow many elements does it contain?

Answer: Third option is correct.Step-by-step explanation:Since we have given byEvent A: the red die shows 1Event B :  the numbers add to 4Event C: at least one of the numbers is 3Event D : the numbers do not add to 9. D' means the number add to 9.We need to write the following statement in symbolic form:Either the numbers add to 9 or the red die shows a 1. So, it becomes,[tex]D'\cup A[/tex]Number of elements in D'∪A = 1.Hence, Third option is correct.
