$\frac{1}{128}$
When a coin is tossed, Total outcomes = 2 Favorable outcomes to get tails = 1 Probability of getting tails = $\frac{1}{2}$ When a coin is tossed six times, probability of being all tails = $\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}$ = $\frac{1}{128}$
