Question 1082115
(i) 5*3*6*4=360 different outfits.
(ii) 5*1*6*1=30, so 30/360 or 1/12 probability.
(iii)4*2*5*3=120 outfits.
(iv) she needs to increase the number by 1/3 (edited) or by 40, to 160. The way to increase by 1/3 is to increase whatever is 3 to 4, and that would be another pair of shoes.  4*2*5*4=160.
