Sorry if I've confused you!!
The stats are different for everyone depending on how many children they are going to have. If someone is going to have 6 children there are many vairables
eg BBBGGG, BBBBGG, BBBBBG, BGGGGG etc.
The more children you are going to have the better the chances of having your desired gender.
SO for you if you asked me when you had 3 boys what were your chances of having a girl when you have 3 go's left (planning 6 children)
you would work it out like this!
Your variables are
BBB BBB
BBB BBG
BBB BGG
BBB GGG
BBB GGB
BBB GBB
( 6 options)
So out of every 6 families who have 3 boys first and plan on having 6 children 5 out of the 6 will have at least 1 girl! Only 1 out of those 6 (you!) will have 5 boys followed by a girl!! You had a 2 out of 6 chance of having 1 girl when you were 3 boys in!!!
You are definitely a lucky lady!!
Hope I haven't confused you more! This is really indulging my joy of the statistics of all this! Anyone else!!!
