To find : Which equations represent functions?
Solution :
Function is defined as the relationship between two variables in which one variable is dependent s.t. for one variable we have the value of other.
From the given options,
A.
This is a function of variable x and y forming a linear equation.
B.
This is not a function as there is only one variable x.
C.
This is not a function as there is only one variable x.
D.
This is not a function as there is only one variable y.

Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.
P=
For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.
P(4)=1/6
Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:
1
2
3
4
5
6
Of the 6 possibilities, 3 are even numbers.
P(even)=3/6 or 1/2
