Question

Two dice, one blue and one grey, are thrown at the same time. Complete the following table:
From the above table a student argues that there are 11 possible outcomes 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. Therefore, each of them has a probability . Do you agree with this argument?

Answer 1

Argument is incorrect

Step-by-step explanation:

The completed table will be:

Sum of two dice  2     3     4     5     6     7     8     9     10     11     12

Probability     1/36  1/18  1/12  1/9   5/36  1/6   5/36  1/9   1/12   1/18   1/36

We find that each term does not have a probability of 1/11.

So the argument is incorrect.
