Answer is 3:1 becoz when aabbbcc is selfed we get genotype :-AABBCC,AABbCC.
now on taking cases:-
a) crossing between a AABBCC and AABbCC.
we get AABBCC ND AABbCC only. so we get only dominant phenotype.
b) crossing between AABBCC & AABbCC in ratio 1 : 1.
we get a AABbCC only so only dominant phenotype.
so as we get only 2 phenotype &dominant type is more common.
