There were 5 of the 15 in the simulation that used a coupon.  To find the probability you just divide 5 by 15
P(=>4) = 5/15 = 1/3 - probability of 4 or more

Step-by-step explanation:
1) given 
2) 2 non - common sides in 1 ray
3) supplemental
5) opposite angles are congruent
 
        
                    
             
        
        
        
Simply add up all.
4  1/2  +    6  2/3  + 9  1/4
(4 + 6 + 9) +    1/2  + 2/3 + 1/4
19                    6/12 + 8/12 + 3/12 = (6+8+3)/12 = 17/12
19      17/12
 
19       1 5/12
19 + 1  5/12
= 20   5/12
20   5/12    yards was purchased.
