1/6

500

A six-sided die is thrown 50 times. Using the list below, how does the theoretical probability of rolling a 3 compare to the experimental probability of rolling a 3? Number on Die How Many Times it Landed on that Number 

1=8    2=6    3=7    4=12    5=10    6=7

The theoretical probability is higher than the experimental probability. (Theoretical = 17%, Experimental = 14%)
