The equivalent expression to the given expression is
Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).
From the given expression, we are to determine an expression that is equivalent to:
To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.
By doing so, we have:

Answer: The required probability of having 6th girl is 0.5.
Step-by-step explanation: Given that boys and girls are equally likely.
We are to find the probability of a couple having a baby girl when their sixth child is born, given that the first five children were all girls.
Since the events of having a boy and a girl are independent of each other, so
the probability of having 6th girl dose not depend on the birth of the first five girls.
We know that there are only two possible cases (either a boy or girl will born).
So, sample space, S = {G, B} and the event E of having a girl is, E = {G}.
That is, n(S) = 2 and n(E) = 1.
Therefore, the probability of event E is given by
Thus, the required probability of having 6th girl is 0.5.
