**Answer:**

The experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).

**Step-by-step explanation:**

**Theoretical probability of number 3 on a die:**

Total no. of possibilities = 6

Probability of getting a 3 on a die each time it is rolled = 1/6

= 0.16667

**= 17%**

**Experimental probability of number 3 on a die:**

Total no. of rounds = 4

Rolls each round = 20

no. of 3s in round 1 = 6

no. of 3s in round 2 = 6

no. of 3s in round 3 = 5

no. of 3s in round 4 = 7

Total rolls = 20*4 = 80

no. of times 3 comes up = 6+6+5+7 = 24

Experimental probability of getting a 3 on a die

each time it is rolled = no. of 3s/total rolls

= 24/80

= 0.3

**= 30%**

**Difference** = 30% - 17% = **13%**

**Experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).**
