Presumably our goal is to show PRQ=SRQ, PQR=SQR and QR=QR for ASA.
A. QR=QR is the reflexive property; things are congruent to themselves, TRUE
B. We need to prove that, but it doesn't have anything to do with the symmetric property.
C. PQ=SQ isn't something we'd need to show for our ASA proof
D. Again, not the symmetric property.

Answer:

Step-by-step explanation:
In probability,
"AND" means "multiplication"
"OR" means "ADDITION"
We want probability of Blue Pen and Yellow Highlighter. So we find individual probabilities and "MULTIPLY" them.
Let P(b) be probability of blue pen
Let P(y) be probability of yellow highlighter
We know probability of event is that event divided by total number of that
So,
There are 4 + 2 = 6 pens
Blue pen = 2
Hence,
P(b) = 2/6 = 1/3
And,
There are 5 highlighters
Yellow highlighter = 1
Hence,
P(y) = 1/5
Now,
P(b and y) = 1/3 * 1/5 = 1/15
Hence,
probability of grabbing blue pen and a yellow highlighter is
