Where can I find distribution for independent films?

Find the indicated probabilities using the geometric distribution or Poisson distribution.?

• Find the indicated probabilities using the geometric distribution or Poisson distribution. Then determine if the events are unusual. If convenient, use a Poisson probability table or technology to find the probabilities. A newspaper finds that the mean number of typographical errors per pad is eight. Find the probability that (a) exactly six typographical errors are found on a page, (b) at most six typographical errors are found on a page, and (c) more than six typographical errors are found on a page. Thanks in advance!

• Answer:

  mean m for the poisson distribution = 8, and formula is P[x] = e^-m *m^x/x! a. P[6] = 0.1221 <------ b. P[≤6] = 0.3134 <-------- c. P[>6] = 1 - P[≤6] = 0.6866 <-------
