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 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!

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

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.

About half the babies born are boys.

To find the experimental probability, you need to determine the number of outcomes in favor of the desired event (the next baby being a girl) and divide it by the total number of possible outcomes.

In this case, the number of girls born is 50. Since there are a total of 40 boys and 50 girls, the number of possible outcomes is 40 + 50 = 90.

Now, you can calculate the experimental probability of the next baby being a girl by dividing the number of girls by the total number of outcomes:

Experimental probability of a girl = Number of outcomes in favor of a girl / Total number of outcomes
= 50 / 90

Simplifying the fraction, you get:

Experimental probability of a girl = 5/9

Therefore, the experimental probability that the next baby born will be a girl is 5/9.

4/5

It's still 1/2.
