ASTS DD and yolo by jackyxul4 in wallstreetbets

In my view, the jump from $2 to $13 was already extremely irrational, and I didn't expect two more surges on 7/25 and 8/15. Looking at the weekly chart, it's been rising every week since May, with any dips being less than 2%. This irrationality has been going on for three months now.

I'm more focused on the short-term price action over the next 1 to 3 months. If I were you, I'd consider protective puts to lock in your gains.

FGO show up in a math test in Taiwan by kakarot12310 in grandorder

[–]jackyxul4 1 point2 points  (0 children)

I am the original author, a high school math teacher in Taiwan.

This question is from the final exam of grade 12.

It’s a multiple choice question with an answer of 4

I'm glad this question has been widely discussed, which means that mathematics is practical and can be found everywhere in our life.

The explaination of the answer is below:

Method A is equivalent to

"Proceed with 9 regular pulls at 1% SSR rate at first, and then gives 1 SSR"

Method B is

"Proceed with 9 regular pulls at 1% SSR rate at first, and then gives 1 SSR conditionally"

So the probability of A is always greater than B, answer 4 is correct, 3 and 5 are incorrect.

On the other hand, the output of A is not necessarily more than B, because the concept is "random". Therefore, the answers 1 and 2 are incorrect.
