A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.

Here we have the table:

x y

4 2

3 3

4 5

5 6

7 7

As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.

Then this table does not represent a function.

A bag contains 10 marbles:

Len [333]

Total number of marble = 10
3green
2red
5 blue
Probability that the first marble is red = 2/10

Probability that the second is blue = 5/9(a reduction in the total number of marbles, because after the first marble was picked it wasn't replaced)

Probability of 1st and 2nd being red and blue respectively = 2/10 × 5/9
=1/9....

Hope this helped...?
