Answer:
9 red tiles
Step-by-step explanation:
Total number of tiles: ![6+8+6=20](https://tex.z-dn.net/?f=6%2B8%2B6%3D20)
Total number of red tiles: ![6](https://tex.z-dn.net/?f=6)
Probability of getting red in one draw: ![\frac{6}{20}=0.3](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B20%7D%3D0.3)
<em>This means that you would expect to get red
or 30% of the times.</em>
<em>Hence, when you draw tiles 30 times from the bag, you would expect red to be picked 30% of 30 times. This is:</em>
<em>
</em>
So, you would expect to draw a red tile from the bag 9 times.
i think the answer is 8
