Students attending an international event were asked if they can speak Arabic or Chinese. 25% speak Arabic, 20% speak Chinese, 10% speak both languages. Assume random selection: a. What is the probability that the student can speak Chinese or Arabic? b. What is the probability that the student cannot speak Chinese or Arabic?
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.
![**Language Proficiency Analysis at an International Event**
At an international event, students were surveyed about their language skills, specifically their ability to speak Arabic or Chinese. The results are as follows:
- 25% of the students speak Arabic.
- 20% of the students speak Chinese.
- 10% of the students are proficient in both languages.
Based on these statistics, consider the following probability questions, assuming a random selection of students:
a. **Probability of Speaking Chinese or Arabic:**
- We are interested in determining the probability that a randomly selected student can speak at least one of the two languages: Chinese or Arabic.
b. **Probability of Not Speaking Chinese or Arabic:**
- This involves calculating the probability that a student cannot speak either Chinese or Arabic.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd1bdfc6b-3679-432b-9f52-bc86f2f36147%2F60cfb2cf-d827-4550-9821-b8ff7249a665%2F48757uk_processed.jpeg&w=3840&q=75)
