Answer:
venn diagram, counting method and tree diagram.
Step-by-step explanation:
1. Venn diagram:- A venn Diagram is pictorial representation of the relationship betwwen sets.In venn diagram , the sets are represented by oval shape and circles.The elemements of sets are labelled within the circle.For example ,
A set P is the collection of even numbers between 1 to 10. Then the venn diagram of set P
Where U= Universal set = collection of all numbers from 1 to 10.
2. Counting method :- in this method simply counting the possible outcomes of any event like as tosses a coin and rolled a dice etc.
3.Tree diagram :-let a coin tosses then tree given below

Answer:
Part 19) x=5
Part 20) x=-3
Step-by-step explanation:
Problem 19) Find the value of x so that f(x)=7
step 1
Find the intersection point of the given line in the graph with the line y=7
The intersection point is (5,7)
see the attached figure
therefore
The x-coordinate of the intersection point is the value of x when f(x)=7
x=5
f(5)=7
Problem 20) Find the value of x so that f(x)=7
step 1
Find the intersection point of the given line in the graph with the line y=7
The intersection point is (-3,7)
see the attached figure
therefore
The x-coordinate of the intersection point is the value of x when f(x)=7
x=-3
f(-3)=7
