Aspinner is divided into 4 equal size sections. the 4 sections are colored red green orange and blue. if ana spins the spinner twice what are the possible outcomes?

There are 4 possible outcomes with the same colour:-
RR, OO, GG and BB.

The rest of the outcomes = number of permutations of 2 from 4 which is 

4*3*2*1 / 2 = 12   ( I am assuming that the order in which they appear does matter)

Soi the total ways = 12 + 4 = 16

The percent increase is 25%
