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%).
