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.

EXPLANATION
We want to approximate, using the ALEKS calculator, the value of:
To do this, we input the radical and the number into the calculator. The result is:
Since we have to round the answer to the nearest hundredth, we will pick the number in the thousandths place value, which is 3.
This number is less than 5, so, we round it down to 0 and add it to the number in the hundredth place value, which is 8.
Hence, the answer is:
