In a family with 3 children what is the probability to have one girl

Probability is a measure of the likeliness that an event will occur.

Probability is used to quantify an attitude of mind towards some proposition of whose truth we are not certain. The proposition of interest is usually of the form "Will a specific event occur?" The attitude of mind is of the form "How certain are we that the event will occur?" The certainty we adopt can be described in terms of a numerical measure and this number, between 0 and 1 (where 0 indicates impossibility and 1 indicates certainty), we call probability. Thus the higher the probability of an event, the more certain we are that the event will occur. A simple example would be the toss of a fair coin. Since the 2 outcomes are deemed equiprobable, the probability of "heads" equals the probability of "tails" and each probability is 1/2 or equivalently a 50% chance of either "heads" or "tails".

These concepts have been given an axiomatic mathematical derivation in probability theory, which is used widely in such areas of study as mathematics, statistics, finance, gambling, science (in particular physics), artificial intelligence/machine learning and philosophy to, for example, draw inferences about the expected frequency of events. Probability theory is also used to describe the underlying mechanics and regularities of complex systems.

What if the questions ask:
Probability that the family has exactly 1 boy and 2 girls?
Probability that the family has at least 1 girl?

I have 3 boys going for one last baby hoping on a girl though

I have a couple more problems for you:
A family has 4 children, 3 of them are girls, what is the probability that the last one is a boy?

Hello I have a 5 year old boy and another boy that’s almost a year old. If I decide to have another child in a year or two what are my chances I’d have a girl the third time around? Thanks

I didn’t understand B. Why we have to select BBB if it said “At most 2 girls” so that means that we need at least 2 G’s right!? :(
