Answer:
The number of ways of selection of 3 items taking 2 at a time in addition to the possible ways in which each girl selects the same style is 9 different ways. Since the list contains 9 different ways in which each of them can select a style, the list is complete.
Step-by-step explanation:
Here we have the number of ways the available styles can be arranged between each girl is given by the number of permutation of 3 items, taking two at a time plus the number of possible selections where both of them select the same style as follows
We note that the formula for permutation is
P
= 
Therefore ₃P₂ =
= 6 different ways
The number of possible selections where both of them select the same style is given by
(T, T), (s, s), (L, L) = 3 different ways
Total number of ways = 6 + 3 = 9 ways
Number of different ways available in the list = 9 ways
Therefore the list is complete
All I know is that your need to add 15+15 and find the radius of the circle
you all have to fine the circumeference =2 pi r, the area= pi R square
the Radius is 5ft=25ft cuz of the pi r square is 2, pi = 3.14 (value) 3.14*25ft =75 square ft shouled be your answer
