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.

Asks to determine whether or not 6 statements are propositions or not i.e. we can determine a truth value or not.

Student is given two whole numbers to add, they have to give the sum.

The numbers are in the range of -9 to 9.

Two sample t-test to see if there is a difference between scores on questions between two groups when the questions are asked in a different order.

Shows how to use the "random person" extension to pick random names using the built-in French data set.

Shows how to use the "random person" extension to pick random names for people in your questions.

The student is asked to write a matrix with a certain property, or tick a box labelled "this is impossible" if it can't be done.

A custom marking algorithm on the gap-fill part first checks if the student ticked the box. If they did, their answer is marked correct if it really is impossible. If they didn't tick it, their matrix is checked against the required property.

One question on determining whether statements are propositions.

Four questions about truth tables for various logical expressions.
