What is the probability that all children are girls?
So there are 15 possible outcomes left, all with at least one girl, of which one is all girls. So the probability that all four children are girls is 1/15. 16 possibilities, the first one with all boys discarded, so 1 out of 15 is all girls.
What is the probability that the child will be a girl a boy?
So why do some families have all girls or all boys? 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 formula of probability?
P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space….Basic Probability Formulas.

What are the chances of having 8 kids?
Strollers for Octuplets Four-, five- and six-seat strollers are available and could be used in combination to transport eight babies. Get diet and wellness tips to help your kids stay healthy and happy. Raising Multiples. Sextuplet, Septuplet & Octuplet Fact Sheet.
What are the odds of having 10 girls?
The first child can be either sex, after that, there is a 50/50 chance on every birth. Assuming that probability of either gender is 1/2, then the probability of any specific sequence of 10 children is 1 / 2^10 = 1 / 1024 (the probability of every sequence is the same).
What is the probability of having 3 children that are all boys?
Long answer: The chances of having three boys are 1/8. If you learn about only one gender, it must be “boy” so the chances of having three boys, AND knowing about a boy, are also 1/8. The chances of having two boys and a girl are 3/8.
What is the probability that in a family of 3 children there will be at least one boy?
question_answer Answers(3) The probability that each child will be a boy is 1/2. The probability that each child will be a girl is 1/2. The probability of at least 1 boy = 1 – the probability of no boys. boys which = 3/8 + 3/8 + 1/8 = 7/8.
What are math probabilities?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin.
Can you have 8 babies naturally?
For a woman to conceive eight babies naturally, she would need to release maybe four or five eggs (extremely unlikely), and all or most of the eggs, once fertilised, would have to go on to split to form twins or triplets (again, this would be mind-bogglingly rare).
