Radius of circle: 10 0.5

Therefore, only 0 or 2 satisfies the condition.

The sieve is uniform, and the probability of each face is equal, so the probability of 0 or 2 is 2/6= 1/3.

Throwing twice, the number of points that meet the conditions: {0,0}, {0,2}, {2,2}

Probability: 3 *1/3 *1/3 =1/3.

2)

Only 2 points meet the condition, {0,2}

The polygon with the largest area is a circle with a radius of 2.

The probability is the ratio of the areas of two circles, and the probability is π 2 2/(π *10) = 2/5.
