OK now we have probabilities of 0.46 for 3 or more goals and 0.54 of 2 or fewer goals.the no commission implied probability is
The equation you need to solve is:then use the poisson formula here
i guess P < 3 = 0.54
x = 0, 1, 2
e = 2.71828
μ is ur answer
P(x; μ) = (e^-μ) (μ^x) / x!
so u need 0.54=[(2.71828^-μ) (μ^0) / 0!]+[(2.71828-μ) (μ^1!) / 1]+[(2.71828^-μ) (μ^2) / 2!]
can any1 help me solve this or even better where can i find a formula for the mean.
would be amazing if there was something i could use in excel to solve this also.
This almost certainly has no simple closed form solution for so you will need to solve it numerically (or graphically).
