The equivalent expression of 2b + 4 is 2(b + 2) .
<h3>What is an equivalent expression?</h3>
Equivalent expressions are expressions that work the same even though
they look different.
In other words, two expressions are said to be equivalent if they have the
same value irrespective of the value of the variable(s) in them.
If two algebraic expressions are equivalent, then the two expressions
have the same value when we plug in the same value for the variable.
Therefore, let's find the equivalent expression of 2b + 4.
Hence, using common factor,
2b + 4 = 2(b + 2)
Therefore, the equivalent of 2b + 4 is 2(b + 2)

Answer:
1/4896
Step-by-step explanation:
This is a permutation problem, where order matters.
There are 18! ways to line up the class, and (18−3)!=15! ways where three children line up first, second, and third.
Then the probability is
P=15!18!=14896≈0.0002
