Ohhh, sorry about that, I was doing P(1 and 1) P(3 and 3) P(5 and 5) twice by mistake. Thank you!! :smile:


May I just add in (it's two weeks old but..) you could just find the probability that it is odd (so add P(x=1) + p(x=3) + p(x=5)) and then square it and get the same result. So you get (0.62)^2 = 0.3844. It's a bit quicker than finding all the potential ones!

Yep I just saw! I still don't fully get it though, hence another response on the other thread :wink:

Ah, alright. :lol:
Hi, do we include the outlier in calculations?

No? Your post has no context and thus doesn't have a reasonable reply. Plus, you'd be better off posting this in another thread.
