Answer: 3%

Most likely, you won't need to type in the percent symbol since that seems to be already done for you.

=========================================================

Step-by-step explanation:

The outcome "2" shows up 3 times, as shown in the first column. Let A = 3.

Add up all the values in the bottom row: 3+6+8+11+14+16+15+12+9+5+1 = 100. Let B = 100. This is the total number of dice rolls.

Dividing the two values gets us A/B = 3/100 = 0.03 = 3%

The value "2" shows up 3% of the time, which is the experimental probability of getting a "2".
