I need help figuring out the chance of success for completing this “level” game.

Starting with level 1, and making it to the end (level 7)

Given the % chance of “Success” at each level, is it possible to determine the overall % chance to win?

Start

Level 1: 77%

Level 2: 75%

Level 3: 71%

Level 4: 67%

Level 5: 60%

Level 6: 50%

Level 7: 33%

Win

So there is a 77% chance to make it to level 2

Once you are at level 7, there is a 33% chance to win the game.

I want to know if it is possible to figure out the overall % chance to win the game (and how).

Thank you for any & all help !
