So for this, I will be using the elimination method. So firstly, multiply both sides of the first equation by 2 and both sides of the second equation by 3:
Now add the two equations to get . From here you can solve for x. For this, just divide both sides by 17, and your first answer will be
Now that we have the value of x, substitute it into either equation to solve for y:
Answer: Third option is correct.
Step-by-step explanation:
Since we have given by
Event A: the red die shows 1
Event B : the numbers add to 4
Event C: at least one of the numbers is 3
Event 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,
Number of elements in D'∪A = 1.
Hence, Third option is correct.
