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 %
The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.
The probability of two tails on two tosses of a coin is 0.52, or 0.25.
It is 1/8.

To find the probability of getting at least one head in 4 coin tosses, it's easier to calculate the complementary probability of getting no heads at all (i.e., getting all tails). The probability of getting tails in a single toss is 0.5, so for 4 tosses, the probability of all tails is ( (0.5)^4 = 0.0625 ). Therefore, the probability of getting at least one head is ( 1 - 0.0625 = 0.9375 ) or 93.75%.
It is 0.25
The chance is 50%-50% that it will be heads or tails; this does not change regardless of the number of previous tosses and their results.
