1. **Problem statement:**
(a)(i) A restaurant offers a three-course meal with 4 starters, 6 main courses, and 8 desserts. We need to find the total number of different three-course meal combinations.
(a)(ii) Jack finds the restaurant has 4 starters, 6 main courses, but fewer desserts, resulting in 120 different meal combinations. We need to find how many desserts are still available.
2. **Formula used:**
The total number of combinations when choosing one item from each category is given by the product rule:
$$\text{Total combinations} = (\text{number of starters}) \times (\text{number of mains}) \times (\text{number of desserts})$$
3. **Solution for (i):**
$$\text{Total combinations} = 4 \times 6 \times 8 = 192$$
So, there are 192 different three-course meal combinations available.
4. **Solution for (ii):**
Let the number of desserts available to Jack be $d$.
Given:
$$4 \times 6 \times d = 120$$
Simplify:
$$24 \times d = 120$$
Divide both sides by 24:
$$\cancel{24} \times d = \frac{120}{\cancel{24}}$$
$$d = 5$$
So, Jack has 5 desserts available.
**Final answers:**
(i) 192 combinations
(ii) 5 desserts
