This question requires two cases: No horseback riding on Wed and Horseback riding on Wed. The answer is 3^5+3^3 |

All of that over 4^5 right because we are finding probability. |

Since the question is asking for the probability, you need to put your answer over omega. The final answer should be (3^5 + 3^3) / (4^5) |

I agree with lewenchiu, that is the same answer as what I got. |
