1/16
The 1/16 is when there is exactly 4 coin tosses or n = 4.
As the number of trials increases so does the probability of at least 1 run of length 4.

The average number of coin flips to see 4 in a row is 30.
Some other probabilities for different values of n (number of coin flips)

What is the probability of flipping a coin twice and getting two heads?
The probability is 25%. The probability of flipping a coin once and getting heads is 50%. In your example, you get heads twice -- over the course of 2 flips. So there are two 50% probabilities that you need to combine to get the probability for getting two heads in two flips. So turn 50% into a decimal --> 0.5 Multiply the two 50% probabilities together --> 0.5 x 0.5 = 0.25. Therefore, 0.25 or 25% is the probability of flipping a coin twice and getting heads both times.
