Answer:
Probability of randomly drawing a red marble is
Step-by-step explanation:
Given 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. we have to find the 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
As Probability of an event is the chances of an event to occur. It is defined as the favourable outcomes by total number of outcomes.
As no. of red marbles are 5 and
Total number of marbles are 5+8+12=25 marbles.
Hence, probability of randomly drawing a red marble is

To take out terms outside the radical we need to divide the power of the term by the index of the radical; the quotient will be the power of the term outside the radical, and the remainder will be the power of the term inside the radical.
First, lets factor 8:
Now we can divide the power of the term, 3, by the index of the radical 2:
= 1 with a remainder of 1
Next, lets do the same for our second term
:
= 3 with a remainder of 1
Again, lets do the same for our third term
:
with no remainder, so this term will come out completely.
Finally, lets take our terms out of the radical:
We can conclude that the correct answer is the third one.
