I'm not really sure - it's the fraction bit that's tripping me up, and I can't find much information on what an "expected fraction" is. From a post on statistics stack exchange, someone asked a question regarding "expected fractions" and from what I could gather, it was referring to essentially...

The first part of the question asked me to calculate the mean and standard deviation for the number of remain votes in the simple binomial model consisting of total sample size of 2091 people. I believe this is fairly straightforward, it was simply ##E(X) = \mu = 2091(0.5) = 1045.5## votes and...

Summary: I always feel so satisfied when I self-study physics. It takes me time to truly appreciate what I'm learning when I'm under the pressure of university exams, but eventually when I understand it, I love it too. However, I can't explain why I love it. Hey everyone, I appreciate this...

I think part (a) is simple enough. Here is what I have done. (a) ##G=\sigma T^{4}_{s} - OLR## $$ =\sigma (294)^{4} - 160 = 254 Wm^-{2} $$ Part (b) is where I am confused. I think I'm supposed to apply the second relevant equation, in order to get the change in average surface temperature due to...
