question

Write a FORTRAN program segment to compute values of the POISSON distribution given by P(X) = e^-mm^x/x! Assume (1) that X and m are integer variables; (2) that X and m are small enough that no term will exceed the size permitted for a real variable in your computer; and (3) that the function FACT (n) for computing n! is available.

  9. FUNCTION P(X,M) INTEGER X Y = FLOAT(M) P = EXP(-Y) / (M ** X * FACT(X)) RETURN END
  10. FUNCTION P(X,M) INTEGER X Y = FLOAT (M) P = EXP(-Y) * M / X / FACT (X) RETURN END
