The probability of choosing. a green pen is 0.25
<h3>What is probability?</h3>
Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = Expected/Total outcome
If a bag has 3 blue pens, 6 red pens, and 3 green pens, then;
Total pen = 3+6+3
Total pen = 12
If a green pen is chosen, then
Pr(choosing a green pen) = 3/12
Pr(choosing a green pen) = 0.25
Hence the probability of choosing. a green pen is 0.25

A.) Teenagers require more space than smaller children.
First, distribute the 3 into (-4z+5w):
3w+12z-15w+4z
Combine like terms:
3w-15w+12z+4z
-12w + 16z
