Thanks!!If you're not sure what formula this is, try working backwards from the "sample" formulas they've given you. Which one uses in the numerator? Which one also uses in the denominator?
ThanksStart with this...http://en.wikipedia.org/wiki/Poisson_di ... PropertiesQuestion :
Suppose X and Y are independent Poisson random variable , each with the mean 1 , obtain
Sorry silly mistakes ....Assuming the decimal points stand for multiplication, could you please show the steps in your arithmetic with the fractions?
If u know the answer can u please let me know ?That number seems a little low.then p(knows|correct)=p(correct|knows)*p(knows)/p(correct)
Please can u tell what is wrong
My work ........
E(X) = 0
1 = 0
2 = 2/3
var(X) = 2 - 2 = 2/3 - 2/3 = 0
Could u please help me solve this problem by pointing out the mistake12 is not a probability
