Question 2 please only answer a) In a hotel, a guest at a wedding pays 100 euros per person for an overnight stay and 10 euros for breakfast. If a guest uses the minibar, the cost is 12 euros. Experience has shown that wedding guests book as follows: • 80% book an overnight stay with breakfast • 15% also use the minibar in addition to the booked overnight stay with breakfast • 5% book an overnight stay without breakfast and do not use the minibar either a) A total of 80 guests have announced their wedding at the hotel. - What is the overall turnover of these guests? - Calculate a measure for the theoretical fluctuation in the turnover of a guest. What is your calculated measure? - What is the approximate probability that the total turnover of these guests is over 8,860 euros?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

- Calculate a measure for the theoretical fluctuation in the turnover of a guest. What is your calculated measure?
- What is the approximate probability that the total turnover of these guests is over 8,860 euros?
- What is the maximum total turnover of these guests with a probability of 93%?
