Question

PLEASE HELP ME!!!!!!!

Slowhan decides to play a very fun game. He starts off with his favorite
odd integer. For every turn, Slowhan will either add 1 or subtract 1 to his current number.
What is the probability that after 11 turns, the resulting number will be odd?

Answer 1

The answer is the 11th turn or the other guy answer is right

Answer 2

Answer is even on the 11th turn unless Slowhan is allowed to skip a turn.

4 = odd

5 = even

6 = odd

8 = odd
