What is P(A), the probability that the first student is a girl? (3/4)What is P(B), the probability that the second student is a girl? (3/4)What is P(A and B), the probability that the first student is a girl and the second student is a girl? (1/2)
The probability that the first student is a girl is (3/4), likewise for the 2nd 3rd and 4th it's still (3/4). The order you pick them doesn't matter.
However, once you're looking at P(A and B) then you're fixing the first position and saying if the first student is a girl what's the probability of the second student being a girl.
Answer: 
Step-by-step explanation:
Knowing that Mrs. Huynh bought a bag of 3 dozen toy animals. The total number of animals in the bag is:

The cost of the bag was $28.97, so you must divide 36 by $28.97 in order to know the price of each toy animal.
To estimate this quotient, the first round the numbers so that they are easier to work with.
We can say that:

Then:

Therefore, you can estimate that the price of each toy animal is:

To figure this out all you need to do is add all of the grocery bills and divide that number by 4...
Answer:
970 visits
Step-by-step explanation:
Put the numbers where the variables are and do the arithmetic.
visits = 10 -(2.0 × 20) + (0.02 × 50,000)
= 10 -40 +1000
= 970
You forecast 970 Medicare visits.
Answer:
Option D 97 degrees.
Step-by-step explanation:
The given lines BO is parallel to XY and they are cut by a transversal.
Angles 83 and y are on the same side and are interior to the transversal and are called interior angles on same side of transversal .These type of angles are supplementary ,that is they add to 180 degrees.
83+y=180
With y we have 83 added .
Subtracting 83 both sides we have y=97 degrees.
