If you continue tossing the coin forever, it is effectively a certainty. So probability = 1
If you toss it only 9 times, it is (1/2)9 = 1/512 = 0.00195 (approx)
The probability of getting heads on a single coin flip is 0.5. To find the probability of getting heads four times in a row, you multiply the probability of getting heads for each flip: (0.5 \times 0.5 \times 0.5 \times 0.5 = 0.5^4 = 0.0625). Thus, the probability of flipping heads four times in a row is 6.25%.
