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.
Georgia worked overtime on 4 of the 5 days. Her total overtime hours were
... (12-8) +(9 -8) +(10 -8) +(10 -8) = 4 +1 +2 +2 = 9
Then her pay for the week is
... (hours) × (pay per hour)
... = ((7 + 4×8) +1.5×9) × $7.50
... = 52.5 × $7.50
... = $393.75 . . . . Georgia's gross pay for the week
_____
Pay for "time and a half" can be computed by multiplying pay by 1.5 for overtime hours, or multiplying overtime hours by 1.5 and using straight pay. Either way, it is (overtime hours)×(1.5)×(straight pay).

Answer:
$2.50 per movie and $6.50 per video game.
Step-by-step explanation:
The correct answer is $6.50 for each video game and $2.50 for each movie. My work:
3 x 2.50 = $7.50 and 5 x 6.50 = $32.50
32.50 + 7.50 = $40.00
12 x 2.50 = $30.00 and 2 x 6.50 = $13.00
30.00 + 13.00 = $43.00
