Answer:
Step-by-step explanation:
The angle between numbers on an analog clock is π/6 radians. So, the angles of interest are ...
2 to 9 : seven numbers : 7π/6 radians
3 to 7 : four numbers : 4π/6 = 2π/3 radians
4 to 6 : two numbers : 2π/6 = π/3 radians
1 to 4 : three numbers : 3π/6 = π/2 radians
5 to 10 : five numbers : 5π/6 radians
