Answer:
The probability is Zero
Step-by-step explanation:
There is two possible outcome from a toss of a fair coin = [H,T].
If the coin is flipped seven times, then we have: 2^7 = 128 possible outcomes
However, there won't be outcome in that specific other - [HHHTTTT].
By probability of an event:
Probability = number of event/total number of possible outcome
The event HHHTTTT = 0.
Thus,
Pr[HHHTTTT] = 0/128 = 0.
