Probability of having a pattern in rare subspecies 
Percentage of rare subspecies = 1 % = 0.01
Probability of a beetle with pattern belonging to rare subspecies is

So if you do 3/5 it ends up equaling .6 you can convert that into a percent and it equals 60%

2/3-4/36
24/36-4/36
20/36 also same as 4/9 (D)
2. It's B. (-3*(2*7)=(-3*2)*7
3. -4+(-6)*(-3)
-4+18
-14 (b)
