Number of regular polygon that can be drawn with a number of sides 3 through 10 = 8
Using the formula to calculate internal angle of regular polygon = (n-2)*180/n
When n = 6, measure of internal angles = 4*180/6 = 120
Regular polygon with a number of sides from 6 through 10 will have internal angles will be greater than 110°
Hence, there are 5 regular polygons
Required probability = 5/8
Takeaway: Formula to calculate internal angles of regular polygon = (n-2)*180/n
