First off, hi! I've never been to this forum, but would like to humbly request help on something a little over my head.

1st problem at hand:

I'm going to poke something with a sword 100 times in a video game.

On each of these pokes, I have a 1 in 3 chace of dealing a critical strike.

How many times will I get 3 critical strikes in a row out of my 100?

2nd problem at hand:

After I get 3 critical hits in a row, I'm sure to get a 4th. That 4th can then count as the begining of getting 3 critical strikes. How many times am I likely to get 3 in a row now?

Any help would be greatly appreciated.

Thank you!
