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

The king comes from a family of three children What is the probability that he has a brother?
The probability of a boy (male) is equal to the probability of a girl (female) which equals 1/2. The king is a male. So, we need the probability of a male and a male which is 1/2 * 1/2 = 1/4.
What is the probability that a coulple with three children will have three boys?
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 boy is approx 0.52, the probability that all three children are boys is approx 0.1381
What is the probability that a family of 4 would have 3 boys and 1 girl?
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 boy is approx 0.52, the probability of three boys and a girl is 0.2669.
What is the probability to have 2 girls and a boy in a family?
The 8 possible outcomes for three children are: * ggg * ggb * gbg * gbb * bgg * bgb * bbg * bbb Of these, two girls and a boy occurs 3 out of 8 times, which is a probability of 0.375. This assumes that the probability of a boy and girl being in the family is equal, which is not entirely true for a large number of reasons.
What is the probability of getting three boys out of three children?
I wouldn't say it's very probable. My neighbor has three children and they're all boys. It just depends on the mother and father.
What is the probability of a family with six children having three boys and three girls?

If a family has three children find the probability that two of the children are girls?
there is a 50% chance that two of them will be girls

It is 3/8.

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.

What is the probability that a couple with three children will have at least one girl?
The individual probability that a child born will be female is 50% or 0.5.Using this we can calculate the probability that at least one of the children will be female by:calculating the probability that none of the children will be female and then subtracting this from 1.The probability that all the children are male is therefore 0.53 = 0.5 * 0.5 * 0.5 = 0.125.Thus the answer is 1 - 0.125 = 0.875 = 87.5%
What is the probability of a family that has three children each choosing a cat from a hamster cat dog or rabbit?
1/4 x 1/4 x 1/4 = 1/64 or 1.5625%

If a couple has three daughters what is the probability that the next child is a son if they already have three daughters?
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.If you believe that the children's genders are not independent then you would need to get empirical evidence from all families with four or more children in which the first three children were girls. If there are g families in which the fourth is a girl and b where the fourth is a boy then the required probability is b/(g+b).However, if you assume that the children's genders are independent events then, given that the probability of a boy is approx 0.52, the probability of the fourth child is a boy is 0.52
