To find the experimental probability, compare the total number of times the event occurs to the total number of trials. Compare the frequency of rolling the number six (9) to the total number of trials (60) using a ratio, and then reduce.
If Quincy finds 120 shells in 4 days, we can use the equation 4x = 120 to find how many shells she found each day.
4x = 120
If we divide both sides by four we get x = 30
So Quincy found 30 shells each day.
