You haven't given any definition of what T and N are in relation to the trapezoid (nor really identified which points are which on the trapezoid, though we can infer some of this from step c). So we can't provide a justification for most of these steps. 

(c) is presumably because they're the parallel sides of the trapezoid. 
For (d) I can only think that T, R and I are on the same line, in which case the angles TRG and TIA are congruent because RG and IA are parallel, so they are corresponding angles. 
For (h), I assume by vertical you mean opposite (it's also called vertically opposite). Vertical angles are always congruent. You just said they're vertical, so this follows. 

For (i), from (f) and (h) we have that corresponding angles are congruent, so the triangles must be similar. From (a) we have that GR = GA, so the triangles are congruent by AAS. 

For (j), we could infer this from (i). However step (i) isn't strictly necessary; we can derive (j) directly from (f) and (h) - indeed this was the first part of the proof of (i).

If you flip a fair coin 4 times, what is the probability that you will get exactly 2 tails
Ilia_Sergeevich [38]

Answer:

<h3>The answer is <u>3/8</u> NOT 50%</h3>

Step-by-step explanation:

One way to solve this problem is to figure out how many ways you can get exactly 222 tails, then divide this by the total number of outcomes you could have gotten. Since every outcome has equal probability, this will be the probability that you will get exactly 2 tails.

How many outcomes are there where you get exactly 2 tails? Try thinking of each outcome as a 4-letter word, where the first letter is "H" if the first coin toss was heads and "T" if it was tails, and so on.

So, the number of outcomes with exactly 2 tails is the same as the number of these words which have 2 T's and 2 H's.

How many of these are there? If we treat all the letters as unique, we'll find that there are 4! different arrangements, overcounting 2! times for every time we only switch the T's around, and 2! times for every time we only switch the H's around.

So, there are <u>4!/2!2!</u> = 6  

​  

<u>4!/2!2!</u>= 6 different outcomes where you get exactly 2 tails.

Altogether, there are 2^4 = 16 total possible outcomes.

So, the probability that you will get exactly 2 tails is <u>6/16</u> = 3/8
