Answer 1

hee-hee!

Explanation:

We just need to look at the chart.

There is one row and one column for 1.

There are six rows and columns.

We count how many spaces that have Xs.

There are 11 spaces that have Xs, meaning that there are 11 favorable outcomes.

The chart is a 6 by 6, meaning it has 36 spaces.

11/36

hope this helps :)
