Option C: 0.8889 is the probability of choosing an orange marble and a green marble.
<h2>Given that:</h2>
- Number of red marbles is 5
- Number of orange marbles is 2
- Number of yellow marbles is 1.
- Number of green marbles is 2.
<h2>Explanation and Calculations:</h2>
So there are in total 10 marbles.
Two marbles can be chosen in 
ways = 90/8
Now the favorable event is when one green marble and one orange marble is chosen. The number of ways this can be done is 
The resultant probability is calculated by:
Thus the needed probability is 0.08889 given by option C.

Step-by-step explanation:
Hope this helps!
If 40 people were surveyed then it is reasonable
Answer:
x = 3, y = 10.
Step-by-step explanation:
The 2 triangles are similar so the corresponding sides are in the same ratio.
x/6 = 4/8
x/6 = 1/2
x = 6/2 = 3.
y/5 = 8/4 = 2
y = 5*2 = 10,
We want to evaluate the expression:
We follow the order of operations: PEMDAS
Since there are no parenthesis(P), we evaluate the exponents(E)
Next is Division (D)
We can then simplify since we have only subtraction.(S)
Therefore:
