The second choice is not a relation.
The first and third choices have multiple (input, output) pairs that have the same input. Such a relation is not a function. Any time you see this, you know the relation is NOT a function.
The best answer is the 4th choice ...
... {(0, -9), (-9, 0), (-3, -3)}
Correct answer is c to the question
Can you show the full picture
If the first die is a 5, the second must be 5 or more in order to have a sum of at least ten.
Assuming it is a six sided die, the two values that would make this true are 5 and 6.
2 values/6 possible would be a probability of 2/6, which simplifies to 1/3
Final answer: 1/3
