What is the probability of having male and female offspring?
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. About half of his sperm will make a boy and half a girl. The sex of the baby depends on which sperm gets to the egg first.
What is the probability of having three girls in a row in one family what is the chance of having a fourth girl in a row?
There is hence a 1 in 2 chance (50\% or 0,5 probability) of either a boy or a girl on each occasion. Therefore, by the multiplication principle, the probability of having 3 girls in a row is 12×12×12=18 . The sex of the 4th child is independent of the sexes of the previous 3 and hence is once again 12 .
What is the probability of a family having 2 boys and 2 girls?
There are 4C2 ways to have exactly 2 boys & 2 girls, in any order, so this gives 6/16 =3/8 as the correct probability.
What is the probability for having two children?
It there is a 50\% chance that we will be told the first child is a boy, when there is one of each gender, then the probability of two girls is 50\%.
What is the probability of having a boy with 50\%?
As there is a 50\% chance the child is a boy, we can multiply by 50\% to get the probability of selecting a boy if the newborn is a boy. If the child born is a girl, then there will be g + 1 girls, 3 boys, and a total of g + 4 children.
What is the conditional probability of selecting a boy?
The conditional probability of selecting a boy will be 4/7. Multiplying by 50\% gives a 2/7 chance of selecting a boy and having a boy born. There is also a 50\% chance the child born is a girl. In that case there will be 4 girls and 3 boys. The conditional probability of selecting a boy will be 3/7.
What is the probability of having 3 girls and 3 boys?
There are 64 possible gender birth orders, with 20 of these resulting in you having three girls and three boys. The terms p and q are the individual probabilities for a specific outcome from a single “event”. For “gender” calculations, the probabilities p and q are equal, both = 1/2 (the equal probabilities of male and female births).
