Answer:

75%, or 3/4's

Step-by-step explanation:

Parent's genotypes are Bb because they are homozygous & brown hair is dominant. Cross this, and you get the genotypes of the offspring: BB, Bb, Bb, and bb. The proability that offspring will also have brown hair is 3 out of these 4 genotypes, so 75%.
