Fatima rolls a fair six-sided die and a fair four-sided die simultaneously. The sample space of all possible outcomes is shown below. Let $A$ be the event that the six-sided die is five and $B$ be the event that the sum of the dice is four or less. **What is $P(A\text{ or }B)$, the probability that the six-sided die is five or the sum of the dice is four or less?** [[☃ input-number 1]] $\qquad$
