Printing errors in the work produced by a particular film occur randomly at an average rate of p per page.
i.What is the probability that a one page document will contain x1 printing error(s)?
ii.If a n page document is printed, calculate the probability of having more than x2 errors. Assume a Poisson distribution. -

Question in Bill's workspace
Given a population size and data on a test for a condition on that population, use a tabular approach to find the increase in risk after a positive test in which there is a small chance of a false positive i.e. the probability that the test is positive even though the condition is not present. See Advice for a graphical version.

Question in DemosAn interactive experiment about probability: the student must first 'design' the experiment by deciding how many times they're going to flip a coin, and define what number of heads would make them believe the coin is biased. They must then enter the results of their coin flips, calculate the percentage of heads, and finally decide if the coin is biased, using the condition they specified in the design stage. There are optional hints at each stage.
