step 1
Find the probability that the arrow will land in region A
P=3/8
step 2
Find teh probability that the arrow will land in region D
P=1/8
therefore
the probability in percent form that the arrow will land in region A and then spun again land on D is
P=(3/8)(1/8)=3/64
convert to percent
(3/64)*100=4.69%
answer is 4.69%
