i seemed to have gotten the first part of the probability 1 wrong.

the second part was just finding the complement of the first. If i did that would i still get the mark?

It would be counted as a carry on error, so I think you would probably get the mark.

Yeah, if you've made the mistake once they take it into account and provided you know what you're doing in the next part you'll get the marks

You'd lose the mark for the first question, but get all subsequent marks due to carry on errors (if your working out was henceforth correct).

FUUUU I couldn't get part (i) and I knew I needed the right answer for (i) to answer part (ii) but I couldn't get part (i) so I just left out part (ii) fuuuuuuck

does anyone remember their answer to part (iii) of the probability question?

probability that exactly one ball is not selected.

Not sure what the answer was but for (ii) you need to find the probability for either of the 7 beads not been taken out, for (iii) a specific one must not be picked out, I was thinking you just divide it by 7 but not sure
