In order to solve or know the probability of having 2 girls
and 2 boys, assumed that a girl is as likely as a girl at each birth, pascal’s
triangle will be likely used. And we will be referring to the line 4 of pascal’s
triangle, which was 1 4 6 4 1. Then it
will look like this: 1 = 4 girls; 4 = 3 girls & 1 boy; 6 = 2 girls & 2
boys; 4 = 3 boys & 1 girl; 1 = 4 boys. And now for the solution in order to
get the probability of having 2 girls and 2 boys is to divided into the sum of 1+4+6+4+1.
C because the x's repeat with the 3 and 3. If the x's repeat it is not a function.
Hope that helps.

If a bagel costs $0.80 any day, then the unit price
is $0.80 per bagel.
If the unit price of a bagel is $0.80 , then every bagel
you buy costs $0.80 .
Only one thing changes: The price of a dozen on Wednesday.
If you buy 1 dozen ... or any number of dozens ... on Wednesday,
then the unit price of the contents of that bag is
($6.00) / (1 dozen) = $6.00 per dozen
If you want to convert that to a
different unit of measure, then
you do it like this:
(6.00 $/dozen) x (1 dozen/12 bagels)
= (6.00 x 1 / 12) ($/bagel)
= 0.5 $/bagel
or $0.50 / bagel .
