2. <span>Draw a perpendicular line in any of the four directions to one side of the square.</span><span />

3. <span>Two apothems of a square (drawn to opposite sides) make a line that is parallel to both (left) sides of the square, a line that is of equal length. If two apothems added together are equal to the length of one side, then one apothem is half of the length.</span>
<span /><span>

Answer:

D. 0.5

Step-by-step explanation:

There are 4 groups

1. Alto

2. Bass

3. Tenor

4. Soprano

The question says "what is the probability that this member comes from the alto section"

Since there are 4 groups, I did 4/8 (since there are 8 people in Alto) and I got 0.5.

Hope I got it right and it helped you

*Note* I most likely got it right I just doubt myself too much lol

But just in case, I hope I got it right.
