Answer:
0.9375 = 93.75% probability that at least one of the four children is a girl.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
We have the following sample space
In which b means boy, g means girl
b - b - b - b
b - b - b - g
b - b - g - b
b - b - g - g
b - g - b - b
b - g - b - g
b - g - g - b
b - g - g - g
g - b - b - b
g - b - b - g
g - b - g - b
g - b - g - g
g - g - b - b
g - g - b - g
g - g - g - b
g - g - g - g
Total outcomes
There are 16 total outcomes(size of the sample space)
Desired outcomes
Of these outcomes, only 1(b - b - b - b) there is not a girl.
So the number of desired outcomes is 15.
Probability:

0.9375 = 93.75% probability that at least one of the four children is a girl.
Answer:
Step-by-step explanation:
Since the number of bagels sold already is 47, the total number of bagels sold will be b+47. The revenue from each sale is $0.85, so the total revenue will be ...
A = 0.85·(b +47)
This equation can be written in different forms, but this satisfies the requirement for "an equation."
__
Since b is the number of addition bagels, when 122 additional bagels are sold, the value of b is 122. Then the equation becomes ...
A = 0.85·(122 +47)
A = 0.85·169 = 143.65
Revenue will be $143.65 when 122 additional bagels are sold.
Answer:
The second number line represent the location of 3N values.
Step-by-step explanation:
The first number line represent the inequality <em>N</em> > 3.
Now, the new number is 3<em>N</em>.
Consider the second number line values:
3N = {12, 15, 18, 21, ....}
The second number line represent the location of 3N values.
