Answer: Second Option
20%
Step-by-step explanation:
We have 5 red marbles, 8 blue marbles and 12 green marbles in a bag.
In total there are 5 + 8 + 12 = 25 marbles
This means that the experiment "get a marble out of the bag" has 25 possibilities.
Then, the chances of getting a red marble are 5, because there are 5 red marbles.
Finally the probability of drawing a red marble is:
[tex]P_{red} = \frac{5}{25}\\\\P_{red} = \frac{1}{5}\\\\P_{red} = 0.20[/tex]
[tex]P_{red} =20\%[/tex]
