If 100 couples are selected, what's the chance of them having or not having a girl?

I'm doing this question for a stats class. I'm hoping to find more than just answer, maybe some direction as well. Thank you!If 100 couples are selected, what's the chance of them having or not having a girl?
Your Question is incomplete





Note all Probabilities add to 1





If 100 couples have children what is chance of them having having a girl?


Let P(G) be the probability of a couple having a girl





P(nG) + P(G) = 1





(1-P(G))= P(nG)


(1-P(G))^100= p(ng) probability of 100 couples not having a girl





1-(1-P(G))^100 = p(g) probability of at leased one girlIf 100 couples are selected, what's the chance of them having or not having a girl?
Should be a 50/50 chance of them having a girl. Unless they want you to factor in infertility and stuff, there's something to screw up your results. So yeah, 50%. I really don't have enough background from your question.
Do they all have kids? Will any of them have more then one kid?





If each of the 100 couples has a child, then there is a 50% chance.
im gusseing 1to2
If all 100 couples had one child, the odds of any one of them having a girl would be 1/2. The odds of a particular couple having a girl would also be 1/2. The odds of all 100 having a girl would be 1/2 to the 100th power.
it would be 1/2 or 50%...even if there were only 13 couples for example it would still be 1/2 or 50%....if the couples are each only having 1 child...
Actually it's about 45/55 in favour of the male being born. I am not quite sure, though I heard some (probably spurious) story that male sperm swim faster, but there is definitely a *slightly* higher chance of a male child. You would want to factor in many things. If it's a girl, or non-girl than nothing is still non-girl. 20% average chance of conception. So 20% of 45 and 20% of 55 are your answers for male and female.





Good luck!
