The probability that there will be 3 or more air accidents

-in a given month of the next year = 0.5768

-in 4 of the first 6 months of the next year = 0.2974

-for the first time in the next year on a day of May = 0.0185

-for the second time in the next year on a day of March = 0.2066

Let W be the waiting time (in month) until the 10^th air accident occurs. What is the distribution of W (name and p.d.f.) and what are the parameter values of this distribution? Interpret these parameters.
