If the question was to select at-least 1 pair of each color.
Assume that in the first 2 picks she got pair of blue, in the next 2 picks she got pair of red,in the next 2,pair of gray.So in total 6 picks she got all the 3 pairs. But she is in darkness and is not sure what she picked is enough.So to be 100% sure, she considers herself as she picks all blue first(worst case).Then all the gray. So in the next 2 picks she is sure that she got atleast pair of red. So a total of 25+9+2=36 picks [ans].
