When a certain biased coin is flipped six times, the probability of getting heads exactly twice is not equal to $0$ and is the same as that of getting heads exactly three times. Let $\frac{i}{j}$, in lowest terms, be the probability that the coin comes up heads in exactly $4$ out of $6$ flips. Find $i+j$.
