What is the probability of at least one boy and at least one girl?
The probability of having at least one boy is the probability of any case except four girls = 1 – 1/16 = 15/16. The probability of having at least one boy and one girl is the probability of any case except either of the two extremes = 1 – 1/16 – 1/16 = 14/16.
What is the probability that at least one child is a boy?
78
Probability of having at least one boy is 78.
What is the expected number of female children in a family?
Since each family has 3 children altogether, and we expect half of them on average to be girls, we expect on average 32=1.5 girls per family. Each child has a 12 probability of being a girl. This is the expected number of girls among each one of the three children.
What is the probability that the child will be a girl a boy?
Each time a sperm meets an ovum, there is a 50% chance that it will make a boy and a 50% chance that it will make a girl.
What is the probability of having at least?
To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none).
What is the probability that when a couple has four children at least one of them is a boy?
This problem has been solved! Find the probability that when a couple has four children, at least one of them is a boy. (Assume that boys and girls are equally likely.) The probability is nothing that at least one of the four children is a boy.
What is the possibility of having a girl?
Almost everyone has around a 50% chance of having a boy and a 50% chance of having a girl. What we can say is that dad’s sperm determines whether a baby will be a boy or a girl.
Is it better to have boy or girl first?

How can I increase my chances of having a baby girl?
According to this method, to increase the chance of having a girl, you should have intercourse about 2 to 4 days before ovulation. This method is based on the notion that girl sperm is stronger and survives longer than boy sperm in acidic conditions. By the time ovulation occurs, ideally only female sperm will be left.
