10=25, and as there are 2, 4, 6, 8 but only 5, no. of 5 should be way less than that of 2, so just count how many 5 there're in the final multiplication would suffice.
To count that, it is equivalent to counting no. of possible paths from the square containing 5 to the final one. It needs 4 steps to the left and 3 to the right. So ans=C(7, 3)=35

Notably, you can find the precise number pretty quickly as well, it is 11273214355356217781. It follows the same logic as the video, except the video is only tracking how many times 5 divides into each number. Back of the envelope approximation with tell you youre pushing 80 digits even without the truncated zeros information.

Simple solution. You pull the lever nomatter what. If there is a problem with the experiment, you dont waste time and figure out with convoluted solutions whether its safe to proceed or not.

How can you say that all the zero at the end got cut of even with out making the room smaller or making the rabbits larger? You can only say that all the zero at the end was fake.

This company is called Nano-Rabbits experimenting their new creation.
But have you seen the one who put the virus there in the first place? I wonder what their company is. 1: 25

Why are you all damn crazy about pulling the lever right away? This is just a riddle, to train our minds not to find the literal answer but to answer what the question is.

If anyone wants to know, if you multiply it all out the final number is 6. 649x1080 (using matlab)
Yea sure pull the lever or whatever to be safe in real life.

Simple answer: If you're performing a world threatening experiment and you're no longer sure how it will end. it's not worth the risk. Pull the lever already
