If two dice are thrown, and you sum the digits. What number has the highest probability of appearing?

7

Because there is a lot of ways to get 7 on dice

7 has the highest probability

Explanation:

When two dices are rolled simultaneously,

The possible outcomes are:

{1,1}, {1,2}, {1,3}, {1,4}, {1,5}, {1,6}

{2,1}, {2,2}, {2,3}, {2,4}, {2,5}, {2,6}

{3,1}, {3,2}, {3,3}, {3,4}, {3,5}, {3,6}

{4,1}, {4,2}, {4,3}, {4,4}, {4,5}, {4,6}

{5,1}, {5,2}, {5,3}, {5,4}, {5,5}, {5,6}

{6,1}, {6,2}, {6,3}, {6,4}, {6,5}, {6,6}

The sum of digits are

1 2 3 4 5 6 7

2 3 4 5 6 7 8

3 4 5 6 7 8 9

4 5 6 7 8 9 10

5 6 7 8 9 10 11

6 7 8 9 10 11 12

It is noted that 7 is common in every series,

therefore, 7 has the highest probability
