The conditional probability is 1/4.

The probability of tossing a coin and getting heads is 0.5

Zero. Since coins land on Heads or Tails and not numbers.

The probability of tossing 6 heads in 6 dice is 1 in 26, or 1 in 64, or 0.015625. THe probability of doing that at least once in six trials, then, is 6 in 26, or 6 in 64, or 3 in 32, or 0.09375.

It is 3/4 or 0.75

The probability of getting only one tails is (1/2)7. With seven permutations of which flip is the tails, this gives a probability of: P(six heads in seven flips) = 7*(1/2)7 = 7/128
