Well this is what it is a ≈ 6.98
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 ![^{2}C_1 \times ^{2}C_1 = 4](https://tex.z-dn.net/?f=%5E%7B2%7DC_1%20%5Ctimes%20%5E%7B2%7DC_1%20%3D%204)
The resultant probability is calculated by:
![P(E) = \dfrac{Number \:of\: Favourable \:cases}{ Number\: of\: total \:cases}\\= \dfrac{4}{\frac{90}{2}}\\\\= \dfrac{8}{90}\\\\\approx 0.08889](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%5Cdfrac%7BNumber%20%5C%3Aof%5C%3A%20Favourable%20%5C%3Acases%7D%7B%20Number%5C%3A%20of%5C%3A%20total%20%5C%3Acases%7D%5C%5C%3D%20%5Cdfrac%7B4%7D%7B%5Cfrac%7B90%7D%7B2%7D%7D%5C%5C%5C%5C%3D%20%5Cdfrac%7B8%7D%7B90%7D%5C%5C%5C%5C%5Capprox%200.08889)
Thus the needed probability is 0.08889 given by option C.

Answer:
Answer to what
Step-by-step explanation:
<h3>
Answer:</h3>
19.5 inches
<h3>
Step-by-step explanation:</h3>
Let r represent the length of one of the sections of rope (in inches). Then the total length of the original rope is ...
... 8r +28.9 = 184.9
... 8r = 156 . . . . . . . . . . . . subtract 28.9; next, divide by 8
... 156/8 = r = 19.5
The length of each of the sections is 19.5 inches.
