Answer: Choice C) 9/100</h3>
=======================================================
Explanation:
We have these two events
- A = the coin lands on tails
- B = the number cube (aka dice) lands on '2'
The experimental (aka empirical) probabilities of each are
- P(A) = 36/80 = 9/20
- P(B) = 16/80 = 1/5
Note how P(A) is not 1/2 like we expect; however it's fairly close because 9/20 = 0.45 while 1/2 = 0.5 in slight contrast. The experimental probability never 100% lines up with the theoretical probability, but will get closer as you do more trials (due to the law of large numbers). A similar situation happens with P(B). The theoretical probability would be P(B) = 1/6 = 0.1667
Events A and B are independent, which allows us to multiply the probabilities:
P(A and B) = probability of getting tails and rolling a '2'
P(A and B) = P(A)*P(B)
P(A and B) = (9/20)*(1/5)
P(A and B) = (9*1)/(20*5)
P(A and B) = 9/100 which points the answer to choice C
--------------
Slight alternative method:
P(A and B) = P(A)*P(B) = (36/80)*(16/80) = 0.09 = 9/100
this method involves typing (36/80)*(16/80) into your calculator.

Answers:
- Reason 2) Given. Specifically, the diagram shows that the two angles are adjacent and supplementary, which is why the two angles are a linear pair.
- Reason 3) Definition of Linear Pair. As stated above, a linear pair of angles add to 180 degrees (they are supplementary).
- Statement 4)
since the term "right angle" is another way of saying "90 degree angle" - Statement 5)
The upside down "T" symbol means "perpendicular". Perpendicular lines form 90 degree angles at the intersection.
Side note: The double arrow over WY and XV in statement 5 is supposed to be an unbroken line.
