Question

at a city hospital 40 boys and 50 girls were born yesterday. what is the experimental probability that the next baby born will be a girl?
Ms. Sue
It's still 1/2.

I got 55% but do not take my word. I think you should wait for the answer from an actual tutor. I did 50/90 which led me to 55% of babies that were born yesterday were girls. I would still wait for an answer from someone else and not put that until someone with higher credentials confirms it.
Ms. Sue
About half the babies born are boys.

Ms Sue is correct to state that the mathematical probability is 1/2

But according to the "experimental" data of the hospital, it would be 50/90 or 5/9

Silly question!
4/5
It is 50/90 or 5/9 because 40 + 50 is 90. There are 50 of the 90 girls born. Therefore it would be 50/90! Hope that helped
