That makes perfect sense, thank you so much! I understand much better now, that was very helpful.

So, if Z = X - Y, then I'd think the range of values be anywhere from around approximately -60 to 60 (just coming up with numbers at about 6 standard deviations from the original mean, which I know is not all encompassing but even those values have a very tiny nonzero probability in and of...

Homework Statement You measure the weight of each walnut in a big bag of walnuts and find that the probability distribution of walnut weight is a normal distribution with a mean weight <W> = 30 grams and a standard deviation σW = 5 grams. What is the probability that two randomly chosen...

I have this problem as well, but haven't gotten much further than you. I have set k=2pi/wavelength, with wavelength = c/f. I'm a bit torn on how to get x properly. I was thinking that if you have wavelength, and you could find the fraction of the period it was through at that point, you could...
