Which of the following statements about probability models is TRUE? Only one model can be used for a given probability calculation.
Systematic lists are effective models when probability calculations inside the system grid include a single AND statement.
Area models are most effective for complex probability calculations with multiple AND statements.
Tree diagrams are most effective for complex probability calculations with multiple AND statements.

Tree diagrams are most effective for complex probability calculations with multiple AND statements

Step-by-step explanation:

The given statements truths are;

A probability calculation can be calculated by using more than one model, which are dependent on the given parameters which can be either a graphical model such as a tree diagram, or an analytical model such as the systematic list model

A systematic list model is one that lists the possible outcomes of simple events

Area models are used for the representation of simple probabilities

Tree diagram models are helpful in graphically displaying complex probabilities, to aid visualization of the solution.

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

except a rational number. : )
