The probability of Tails on the first toss is 1/2.

The probability of Tails on the second toss is 1/2.

The probability of Tails on the third toss is 1/2.

The probability of Tails on the fourth toss is 1/2.

The probability of Tails on the fifth toss is 1/2.

The probability of Tails on the sixth toss is 1/2.

The probability of Tails on the seventh toss is 1/2.

The probability of all of them is (0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5) = (0.5)7 = 0.0078125

= 0.78125 %
