Answer 2

Answer: higher chance of loss than gain.

Step-by-step explanation: Well let’s see if you add all the marbles together you end up getting 35. Let’s do the first part of the equation 5 out of 35 is the chances of getting gold which is around 14 percent. 7 out of 35 is 20 percent which is the chances of getting silver. Finally 23 out of 35 would be around 64 percent. If it cost a dollar to play you have around a 35 percent chance of winning and a 65 percent chance of losing, so their is a higher chance of losing then profiting.
