Question

Luis rolled a number cube 60 times. He rolled the number 6 four times. Which is most likely the cause of the discrepancy between Luis’s experimental outcome and the predicted outcome? He did not perform enough trials.
He performed too many trials.
He needs to add the number 6 to the number of times it occurred.
He needs to subtract the experimental outcome from the predicted outcome.

Answer 1

Solution:

Number of times Luis has rolled the number cube= 60 times

Number of times the number 6 has been rolled= 4

As the number cube contains number from 1 to 6.

So, if number cube has been rolled 60 times then each of the number or number 6 must have been rolled atleast  10 times.

The cause of Discrepancy between Luis’s experimental outcome and the predicted outcome is that : Option (A) He did not perform enough trials.  

Answer 2

He did not perform enough trials. The more trials you perform, the closer it gets to the predicted outcome.
