What's the answer to this math problem
Answers
75 + 50 + 100 + 25 = 250
Probability of selecting a red marble:
25/250 (since 25 out of 250 marbles are red)
Since the top and bottom of this fraction are both divisible by 25, we can go ahead and divide them both by 25, simplifying to 1/10.
Probability of selecting a green marble:
50/250
Simplifies to 2/10
Simplifies to 1/5.
Probability of selecting a blue or orange marble
(75+100)/250
175/250
Simplifies to 7/10.
To find the probability that each event occurs in order, simply multiply them all together.
Answer:
7/500 or Answer Choice B
Step-by-step explanation:
1. First find the total # of ALL the marbles in the bag. (75 + 50 + 100 + 25 = 250)
2. Then define the percentage of each marble color in said bag.
- blue: 75 out of 250 (75/250) = 30%
- green: 50 out of 250 (50/250) = 20%
- orange: 100 out of 250 (100/250) = 40%
- red: 25 out of 250 (25/250) = 10%
3. Double check that the percentage = 100. (yes)
4. Understand that she could pick the said marble colors not in the order that was specified, so to determine the chances of picking the right colors in the right order. Multiple the values.
red marble: 1/10 chance
green marble: 2/10 or 1/5 chance
blue OR orange (this means add together and then divide by total: 250): 7/10 chance
multiply fractions: 1/10 x 1/5 x 7/10 = 7/500 (this is simplified)
5. Select Answer Choice (B)

You may need to sit down with your parents or with your teacher and
go over how to add and subtract fractions.
1). "Perimeter" means the distance all the way around the square.
With a square, all 4 sides are the same length. With this square,
every side is 1-1/4 inches long.
Perimeter = length of all 4 sides= (1-1/4) + (1-1/4) + (1-1/4) + (1-1/4) =
(1 + 1 + 1 + 1) + (1/4 + 1/4 + 1/4 + 1/4) =
4 + 4/4 = 5 inches .
2). (2-3/8) + (1-7/8) = (2 + 1) + (3/8 + 7/8) =
(3) + (10/8) =
3 + 1-1/4 = 4-1/4 .
3). The difference is (1-1/6) minus (5/6) .
Before you start to do the subtraction, write the (1-1/6) as (7/6) .
Then the subtraction is (7/6) - (5/6) = 2/6 = 1/3 .
4). This one is almost the same kind of problem as #3.
It's another subtraction.
If you need (2-1/4) all together, and you already have (1-3/8),
then the amount you still have to find, or borrow, or buy, is the
difference between those two numbers.
(2-1/4) minus (1-3/8) .
The trick is to write the (2-1/4) in some form that you'll be able to
subtract (1-3/8) from it. When I learned how to do that, it was called
'borrowing', but I think now it's called 'regrouping'.
We need to work on (2-1/4):
-- take 1 from the 2, and change it into fourths.
2-1/4 = 1 and 4/4 and 1/4 = 1 and 5/4
-- Now, take those 5/4, and turn them into eighths.
Each fourth makes 2 eighths. So 5/4 = 10/8.
Now, the (2-1/4) has turned into 1-10/8 .
We did NOT change the value. It's still the same amount
as 2-1/4 , but it's just written in a different way.
And now the subtraction is easy:
(2-1/4) minus (1-3/8) =
(1-10/8) minus (1-3/8) = (zero and 7/8).
You need 7/8 inch more string than you already have.
