Let's say I am attempting to complete a task, and there is a 30% chance of me succeeding for every attempt. Also, let's say I attempt this task twice. What are my chances of success? Would it be 60% Something different? And why?

It's 51%

The chance of failure is 70% each time, or 0.7

0.7 * 0.7 = 0.49 = chance of failure both times

1 - 0.49 = 0.51 = chance of at least one success

Considering it's you, you'll probably think about attempting it, give up, and post the topic "I can't believe some people are stupid enough to attempt this thing, but I won't tell you what it is" on CE.

Seriously? Is that really how it's culculated? And if so, this can be applied to any statistical problem along these lines?

@Forgettable
@Sativa_Rose

Just out of interest, what levels of education do you have in math(s)?

It's funny, I was extremely good at maths when I was young, but stopped studying it at age 15. Just wasn't so interested.

Just some undergraduate math classes that I had to take for my majors like statistics, discrete math, calc 2, linear algebra, etc.
