Question

a restaurant offers customers a lunch special consisting of a salad and a drink. the table shows the options for the salad and the drink.

each possible combination is equally likely to be chosen.

what is the theoretical probability, expressed as a decimal, that an order of a lunch special is for a garden salad and tea?

Explanation:

Step1: Calculate total number of combinations

Use multiplication principle. There are 4 salad options and 5 drink options. So total combinations \(4\times5 = 20\).

Step2: Determine favorable combinations

Only 1 combination is garden salad and tea.

Step3: Calculate probability

Probability formula \(P=\frac{\text{favorable}}{\text{total}}\). So \(P=\frac{1}{20}=0.05\).

Answer:

\(0.05\)
