Test Analysis: Solution: (1) By

Available? 2 points

(two) the probability of not less than 60 points in mathematics is:

? 4 points

What is the number of people with a math score of 60 or above? 5 points

(iii) Number of students with good math scores: Who? 6 points

Number of students with math scores: 7 points.

Assuming that students with good math scores,

Who are the students who do well in math? 8 points

The scores of the two students are:? * * * 10.

Among them, the absolute value of the difference between the two students' math scores does not exceed 10, including,,,, * *. 12 points?

Therefore, the probability that the absolute value of the difference between two students' math scores is not greater than 10 is 13 points.

Comments: This paper mainly investigates the calculation of histogram and classical probability, which is a basic problem.
