**Answer:**

5 possible outcomes

**Step-by-step explanation:**

The possible outcomes of the event L, the item is liquid, are:

**L=** {liquid, less than 25; liquid, 25 to 75; liquid, more than 75}

The possible outcomes of the event B, the item has 75 or fewer calories of fat, are:

**B= **{liquid, less than 25; liquid, 25 to 75; solid, less than 25; solid, 25 to 75}

**The possible outcomes for the union of L and B (L or B) are:**

**L or B = **{liquid, less than 25; liquid, 25 to 75; liquid, more than 75; solid, less than 25; solid, 25 to 75}

**Therefore, there are 5 possible outcomes in the union of L and B.**
