Twenty-seven users completed a task, and each user did so with a combination of two variables, S and V, which can each have a value of "yes" or "no". Pass/fail data was collected for each user with the following results:
S=yes, V=yes: 7/8 users passed
S=yes, V=no: 1/4 users passed
S=no, V=yes: 10/10 users passed
S=no, V=no: 4/5 users passed
