A fair six-sided die has the digits 1,2,3,4,5,6 on its faces.

Question Image

A fair four-sided die has the digits 1,2,3,4 on its faces.

The two dice are rolled simultaneously. The diagram represents the sample space of the possible outcomes.

Let A be the event 'rolling a 1 on the four-sided die', and B be the event 'rolling a 1 on the six-sided die. Find PAB, the probability that you roll a 1 on the four-sided die and a 1 on the six-sided die.
