1 to 2 = 5 to 10 so 15 students in all.

It is 1:1.
2 to 1
ratio is 1:2 in other words for every 1 boy there are 2 girls
Of the total 15 people 5 are boys and 10 are girls Boys are 5/15 = 1/3 Girls are 10/15 = 2/3 Ratio of boys to girls is 1 to 2

about 1 boy to every 2 girls XD
1 boy and 6 girls
It is hard to be precise but the general ratio for anyone to have AS is 1 in 10,000. Boys with AS outnumber girls 4 to 1 in some areas and as much as 10 to 1 in others.
In order to know the answer, you must assume a maximum number of children for each couple or you must assume that the liklehood of having either a boy or a girl is 50/50. Without these constraints then the question makes no sense as: Thus, first child is a boy, they stop. First child is a girl, they have another, if a boy then they stop. Total thus far is 1 - 0 , plus 1 - 1. ratio is 1 boy to 2 girls. But, if first two are girls then a boy, we now have 3 boys and 3 girls, ratio is 1 - 1. But if first three are girls then a boy, we now have a total of 4 boys and 6 girls, then we have 5 boys to 10 girls, then 6 boys to 15 girls and so on. But, if you assume that the odds of having a boy or a girl are evens, then First child is even money, if a boy, stop. First child is a girl, then have another, which by the laws of the 50 / 50 ratio would have to be a boy. So, if the village tribe consists of 100 couples, 50 will have a boy first and stop. 50 will have a girl first, followed by a boy. Total boys = 100, total girls = 50. ratio is 2 - 1.
The ratio was estimated at 1046 to 1000 in 2013.
There is about a 1 to 15 or so boy to girl ratio in North England and 1 to 13 ratio in South England. The ratio in America is 1 to 29.5 girl to boy ratio.
