During an experiment, juan rolled a six-sided number cube 18 times. the number two occurred four times. juan claimed the experimental probability of rolling a two was approximately 1/9. why is juan’s experimental probability incorrect?

Step-by-step explanation:

Given :

Juan rolled a six-sided number cube 18 times.

The number two occurred four times.

To Find: Juan claimed the experimental probability of rolling a two was approximately 1/9. Why is Juan’s experimental probability incorrect?

Solution:

Total events = number of times cube rolled = 18

Favorable events = The number two occurred four times.  = 4

So, Experimental probability =

                                               =

                                               =

Thus the experimental probability of rolling a two was  

So, Juan’s experimental probability was incorrect.
