Answer:
12
Step-by-step explanation:
In my experience, it was a lesson in Grade 8 Math, called possibility.
so Yhana has 3 blouses (criss cross, with lace, sheer, and sleeveless) and 3 skirts (red, pink and black)
so
cris cross-red
-pink
-black
with lace-red
-pink
-black
sheer -red
-pink
-black
sleeveless -red
-pink
-black
total of outcomes: 12
so Yhana can design her outfit in 12 ways.
I hope it helps. :)
