What is the probability of having 3 girls and 3 boys?
If you do out every combination of 6 children:
BBBBBB
BBBBBG
BBBBGB
BBBBGG
BBBGBB etc..., you will find that there are 64 combinations, and 20 of them have 3 girls and 3 boys. (answer=20/64)
What is the mathematical equation to simplify this, as writing that out would take 15 minutes?
Please show the worked problem for the probability of 3 girls and 3 boys, and also for the probability of at least 4 girls. (answer for that one is 22/64)
Thank you
