Which property is illustrated by the following statement 3z+4=4+3z
Answers
The expression 3z+4 = 4+3z represents the commutative property of addition.
What is cumulative property?
The cumulative property states that if the position of the numbers when they are in addition is changed then it will not affect the final result of the addition. If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics.
The commutative property basically states that x+y can be flipped yet have the same meaning so x+y = y+x ~
The given expression 3z+4=4+3z is showing the cumulative property of addition. By changing the position of the additional terms the final result will not change.
Therefore, the expression 3z+4 = 4+3z represents the commutative property of addition.

Answer:
Option d -
Step-by-step explanation:
Given : Event B is dependent on event A, and event A occurs before event B.
To find : Which formula can be used to find the probability of event A?
Solution :
Event B is dependent on event A
i.e. The intersection of A and B - A and B
Probability of event B is dependent on event A is P(A and B)
Event A occurs before event B
i.e. B|A
Probability of event A occurs before event B is P(B|A)
Event B is dependent on event A, and event A occurs before event B is
The formula which shows the probability of event A is
Therefore, Option d is correct.
