A coin-flipping question

Flip a fair coin 5 times and note the results. If the result is either 3 heads/2 tails or 3 tails/2 heads, call the sequence normal. If the result is anything else, a 4-1 or 5-0 split, call the sequence wild.

If you do this procedure 3 times, what are the chances of at least 1 of the sequences being wild?
