What is the probability that at least 1 girl is selected?
The probability “at least one woman” is selected is 1- 1/28= 27/28.
What is the probability of getting a boy in a family of 3 children?
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 is the probability of a family with 3 children containing exactly 2 boys assuming the probability of a boy and a girl are the same?
They would be BBB, BBG, BGB, BGG, GBB, GBG, GGB, and GGG. Out of those, the permutations with two boys and one girl are BBG, BGB, and GBB. The answer is the ratio of how many choices fit your conditions to the total number of possibilities, 38. So the answer is 38.
What is the probability of a family having a girl?
Data from the US and Scandinavia show that the true figure is more like 51% for a boy and 49% for a girl. In addition statistics show that the probability of the child having a specific sex is correlated with the sex of the previous children.
What is the probability of picking a girl?
Answer: Probability of selecting a girl out of 30 children is 13/30 . Please mark this brainliest .
What is the probability of at least one boy and at least one girl?
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 are the odds of having 3 of the same gender?
If you already have a boy, the chance that the next baby is also a boy is 50 percent
| All same sex | Different sexes | |
|---|---|---|
| 2 children | 50% G/B | 50% B/G |
| 3 children | 25% all girl or all boys | 75% BB/G or GG/B |
| 4 children | 12.5% all girls or all boys | 37.5% 1B/3G or 1G/3B |
| 5 children | 6.25% all boys or all girls | 25% BBBB/G or GGGG/B |
What is the probability of having 3 sons in a row?
What is the probability of all three children being girls?
The probability of all three children being girls is the same as that as being all boys, 1 8. And so the probability of the children being all boys or all girls is: P (all boys or all girls) = 1 8 + 1 8 = 1 4

How many possible combinations of 2 boys and a girl?
As we have seen from the other answers, there are 3 permutations out of 8 which contain 2 boys and a girl. But what if we looked at the combinations instead? The combinations of 2 genders among 3 children are: 2 girls, 1 boy can be rearranged, and the boy can have 3 positions (youngest, middle or oldest).
How many different ways can you have a baby?
We know too that of those 8 ways, 2 are for where all three children are the same gender, leaving 6 ways. Of those 6 ways, half will be for having 2 boys and 1 girl and the other half will be for having 2 girls and 1 boy.
