Answer: The percent that you get your first heads on the 6th toss is about 2.26%.

To reach this event, you would have to flip a tails 5 times in a row. Then, you would have to flip a heads.

If we multiplied all the percent together, it would look like:

0.55 x 0.55 x 0.55 x 0.55 x 0.55 x 0.45

Multiplying those gives a value of 2.26%.
