Out of all patients being admitted to a particular ward of a hospital, approximately 16% choose a private room (at an additional cost) versus a semi-private or ward room. However, since there are a limited number of private rooms available, not all patients can have their requests honoured. Today, 17 patients are admitted to this ward, but there are only 3 private rooms available. What is the probability that exactly three patients will request a private room? What is the probability that a patient will not have his/her request for a private room honoured (i.e., at least 4 patients will request private rooms)? What is the expected number of patients that will request a private room today?
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
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
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.

probability that exactly three patients will request a private room? - What is the probability that a patient will not have his/her request for a private room honoured (i.e., at least 4 patients will request private rooms)?
- What is the expected number of patients that will request a private room today?
- Using the
Range Rule of Thumb, what is the approximate range of the number of patients that will request a private room today?
