If the 2nd person pays £52.20, then £52.20 = 3 (from the ratio).
52.20 / 3 = 17.40. 17.40 X 2 (from the ratio) = 34.80.
52.20 + 34.80 = 87.
The meal cost £87.00

Answer: P(3) = 0.20</h3>
====================================================
Explanation:
The Poisson PDF value is given by the function
P(x) = ( e^(-mu)*mu^x )/(x!)
where the exclamation mark indicates a factorial
In this case, mu = 4, so we can update the equation into
P(x) = ( e^(-4)*4^x )/(x!)
Now plug in x = 3 to finish off the problem
P(x) = ( e^(-4)*4^x )/(x!)
P(3) = ( e^(-4)*4^3 )/(3!)
P(3) = 0.1953668148129
P(3) = 0.20
Note: The 'e' is a special constant which is approximately e = 2.718, similar to how pi = 3.14 is a constant used often.
Well I'd say it's any number before or after 11. Since it says 2 more tens it could be 31 by adding. You can also use algebra to help you.
