Answer:
3. rolling a sum of 20 with two standard dice
Step-by-step explanation:
If something has a probability of 0 then there is no chance of it happening
A standard die goes up to 6. The max sum you can get by rolling two dice would be 12 as 6 + 6 = 12. So you have no chance of rolling a sum of 20 with two standard dice therefore the probability would be 0.
Answer:
A function is a relation that for each input, there is only one output.
Here are mappings of functions. The domain is the input or the x-value, and the range is the output, or the y-value.
Each x-value is related to only one y-value.
Athough the inputs equal to -1 and 1 have the same output, this relation is still a function because each input has just one output.
This mapping is not a function. The input for -2 has more than one output.
I hope that helps. I don't know if it is right or wrong, but good luck :)
