Certain events have a 100% probability of occurring, and impossible events have a 0% chance of occurring.
Theoretical probability is based on a mathematical estimate, whereas experimental probability is a probability determined based off of an experiment.
Answer: -5
Step-by-step explanation:Absolute value is +5*-=-5
Let the numbers be x&y
X+y=109
Taking a as the smallest number we multiply by 4
So according to the question you will have this equation
Y(as the largest number) -4x=4. Y-4x=4
Then find y
Y=4x+4
Substitute y on the first equation to get a
X+y=109
X+4x+4=109
X=21
21+y=109
Y=88
