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 
The answer is A..........
Supplementary angles are angles that add up to 180 degrees
Answer = 180 - 142 = 38 degrees
Step-by-step explanation:
To get the perimeter, add up all of the sides.
So, the playground is a rectangle.
It has two sides measuring 58m, and two measuring 91m.
58+58+91+91=298
For the area, length x width
58x90=5278
