Answer:
The probability of a event is a number between 0 and 1 or 1 and 10 or 1 and 100.
Step-by-step explanation:
The correct answer is - The probability of a event is a number between 0 and 1 or 1 and 10 or 1 and 100.
Reason -
Probability - It is a number between 0 and 1
Sample space - All the possible outcomes of an experiment.
Outcome - One of the individual results that can occur in an experiment.
Event: A subset of the sample space
Compound event : A event with more than one outcome.
Divide the number of cars by the number of hours:

Answer:
x = -1 and y = -1
Step-by-step explanation:
Solve 3x+3y=−6;−x+y=0
Steps:
I will solve your system by substitution.
−x+y=0;3x+3y=−6
Step: Solve−x+y=0for y:
−x+y+x=0+x(Add x to both sides)
y=x
Step: Substitutexforyin3x+3y=−6:
3x+3y=−6
3x+3x=−6
6x=−6(Simplify both sides of the equation)
6x
6
=
−6
6
(Divide both sides by 6)
x=−1
Step: Substitute−1forxiny=x:
y=x
y=−1
Answer:
x=−1 and y=−1
