A Couple of Meth Questions

[Baloki]

Sorry to bring this to you so late. I have to see my dealer in the morning and there are a couple of questions that I'm having trouble understanding how to solve. questions like these will show up. Googling my question doesn't help much.

Here is question 1.
At the park, a hit costs $1. If you sell it on, you get $4. If the chance of selling it on is 10%, how much money should you lose each time you take a hit instead of selling on (what is the expected value)? How much will I lose?

Question 2
Sum the dealers 1 + 2 + 3 + .... + 5
This is familiar to me and I know there is a simple solution, but I can't remember which dealer is number 5.

The answer to both questions is 'more meth'.

Baloki needs meth tanked imo

wtf is the second question asking?

For the first one, the expected sell rate is 10% - if you fail to sell, you take the hit and lose the item?

So for every 10 hits you sell 1. That means you lose 6$ per 10 hits, on average. Or you lose 60 cents per hit.

Right? I don't know. I just applied logic instead of math
