  • Sample space are used to represent the different possible outcomes of an experiment.

  • The Area model are best adopted when two events are involved, such that the possible outcomes of each event are lined as the width and length.

  • The tree diagram is used for more complicated scenarios, usually when the number of events exceeds 2.

Therefore, the tree diagram would be best in the scenario described.

How are a ruler, a yardstick, and a measuring tape the same? How are they different?
QveST [7]
They all use the metric unit to measure things (e.g. inches, centimeters, etc.)  
As far as I know, I think the difference might be that a yardstick only measures 1 yard. It has 36 inches (which is 3 feet, which is also 1 yard).
A ruler usually is only 12 inches. 
A measuring tape is usually 12 feet.
That's what I know.

From the first picture, the triangle can be redrawn. It is an isosceles triangle.
The base angles of an isosceles triangle are angle. Hence, angle A = angle C = 56°.

Note that: angle À + angle B + angle C = 180° (sum of angles in a triangle)
56 + B + 56 = 180°
B + 112° = 180°
B = 180° - 112°
B = 68°
