What is the probability that a pregnant woman will give birth to a girl?
A. .2
B. .3
C. .4
D. .5
I'm thinking 1 / 3, or .3
My apologies, it's actually a 50 / 50 chance.
Yep! :-)
To figure out the probability that a pregnant woman will give birth to a girl, we need to consider the probability of having a girl in a single birth.
In human reproduction, the probability of having a boy or a girl is typically believed to be close to 50% each, meaning a .5 probability for either gender. This assumption is based on the fact that each pregnancy involves a random combination of genetic material from the mother and the father.
Therefore, the correct answer would be option D, .5, as it represents a 50% chance or a 1 in 2 probability of giving birth to a girl.
