A pair of dice is rolled 60 times and the sums are recorded. Determine the empirical probability of rolling a sum of 2. 


Expert Answer

Step 1

To find that the empirical probability of rolling a sum of 2 (two).

Definition of Empirical probability:

The empirical probability of an event E is given by, the ratio of the number of times the event E has occurred to the total number of times the experiment has been performed.

Step 2


Let E denotes the event that a sum of two appears on the pair of dice,

If the pair of dice is rolled, sample space is
