It is not possible to give a proper answer to the question because the children's are not independent. Among other things they depend on the parents' genetics and their age and there is no information on either of those factors. Also, the probability of a male child is not 0.5 as it is often naively assumed to be. It is, in fat, around 0.52.
However, if you suspend reality and assume that
- the children's genders are independent and
- the probability of a boy is 1/2
then the answer is (1/2)3 = 1/8.

What is the probability of throwing a 1 a 2 and then a 6 in exactly that order?
If a fair die is thrown often enough, the probability is 1.For the first three throws of a fair die, the probability is 1/216.If a fair die is thrown often enough, the probability is 1.For the first three throws of a fair die, the probability is 1/216.If a fair die is thrown often enough, the probability is 1.For the first three throws of a fair die, the probability is 1/216.If a fair die is thrown often enough, the probability is 1.For the first three throws of a fair die, the probability is 1/216.

It is p3.
What is the probability that a family continue to have children until they have a boy will have more than three children?
The answer to this is 1 minus the probability that they will have 3 or fewer children. This would happen only if they had a boy as the first, second or third child. The probability they have a boy as first child is 0.5 The probability they have a boy as second is 0.25 The probability they have a boy as third is 0.125 Thus the total probability is 0.875 And so the probability they will have more than three children is 1-0.875 or 0.125
When tossing a fair coin the probability of getting three heads in a row is?
In a large enough number of tosses, it is a certainty (probability = 1). In only the first three tosses, it is (0.5)3 = 0.125

What is the probability of exactly 3 girls out of three children?
There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes.However, if you assume that they are independent events then, given that the probability of a girl is approx 0.48, the probability of three out of three being girls is 0.1127.
