Step 1

Given that a dice is rolled 120 times. Here we need to check if it is a fair die. In fair die the probability of occurrence of each number will be same = 1/6.

Using this we calculate the expected frquencies for outcomes as shown below

Step 2

Here we are testing for dice to be fair and we calclated expected frequencies and using the given observed freq...
