The flag

The flag should consist of 3 different colored stripes - available colors: white, red, blue, green, and yellow.
A) number of all flags
B) number of flags with a blue stripe
C) number of flags with a blue stripe in the middle
D) the number of flags that do NOT have a red stripe in the middle

Correct answer:

a =  60
b =  36
c =  12
d =  48

Step-by-step explanation:

n=5  a=n (n1) (n2)=5 (51) (52)=60
b=3 1 (n1) (n2)=3 1 (51) (52)=36
c=(n1) 1 (n2)=(51) 1 (52)=12
