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.
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.

This number is written as a decimal number in a "place value" system, so the position of the digit in the number tells its value.
In order for the 7 to indicate 7 thousand, it needs to be in the "thousands" place in the number. The 0s in the hundreds and units places are called "place holders" because they ensure the other digits appear in their proper places in the number.
