1.

If the teacher calls upon a student to answer a question, what is the probability that the student will be from Kenilworth?
- There are total of 44 students, 8 from Kenilworth. Probability that chosen student will be from Kenilworth will be 8 . 45

4. Find the probability of correctly answering the first 2 questions on a multiple choice test if random guesses are made and each question has 4 possible answers.
- The probability of answering the first 2 questions with 4 different answers each by guessing is 2 or 1 . 10 5

5. Of 1906 people who came into a blood bank to give blood, 300 people had high blood pressure. Estimate the probability that the next person who comes in to give blood will have high blood pressure.
- Based on the past events that have given us the data, the probability that the next person coming into the blood bank has high blood pressure is 5 , which is reduced form of 300 . 44 1906

In my conclusion, having a good understanding of probability can help you make better decisions and sort out the truth behind the numbers. Probability can also be used for fun. Game shows like Deal or No Deal rely
