P(M, n) So if it falls outside the circle according to the conditions, it satisfies m 2+n 2 > 25.

Let me use the form.

If the abscissa is 6, all conditions are met.

The abscissa is 5, and 6 meets the conditions.

The abscissa is 4 (4,4) (4,5) (4,6) that satisfies the condition.

The abscissa of 3 satisfies the conditions (3,5) (3,6).

The abscissa is 2, and the conditions (2,5) (2,6) are satisfied.

The abscissa is 1 (1, 5) (1, 6).

This * * * has 6+6+3+2*3=2 1.

The total * * * basic event is 6*6=36.

So the answer is: 21/36 = 7/12 b.
