Ok, so the probability distribution function is -
P = 1/(σ√2∏)*e^(-1/2((x-μ))/σ)^2
But I'm not sure how to find the standard deviation with the information given? I know its a silly question but I don't understand how to figure it out?
The reason why I want to use the normal distribution is because I know with a larger mean Poisson 'turns' Gaussian. And from a quick look at the bell curve, the answer would be rounded to 1/2. I'm just not sure how to express it mathematically.
1. A 2.5m aperture telescope obverses a star through an R filter. Assume that there is no noise associated with the detection system. The CCD has a full well depth of 20,000 counts and a gain correction factor of 1.00000.
a. On average, the telescope detects 3 photons/sec from this star. What...
