I’m having trouble understanding the statistics interview questions listed here. I’m a beginner in this field and these questions are not making much sense to me.

I’m having difficulty understanding the code for the specific questions. For example, the ‘Probability of at least one success in n trials’ question has some code written and I’m not sure what it means. Here is the code:

```
P = 1 - (1 - p)^n
```

Can someone explain what this code means and how I can use it to understand the question better?

Any help would be greatly appreciated!

Thanks in advance.
