Making Predictions with Experimental Probability

The video tutorial explains how to make predictions based on given data using two examples. The first example involves calculating the probability of hitting a bull's-eye with darts using both fractions and percentages. The second example predicts the number of customers purchasing insurance using percentages. Both examples demonstrate different methods to solve prediction problems, emphasizing the use of fractions and percentages in probability calculations.

What is the main focus of the video?

• Learning how to make predictions based on data

• Understanding the history of darts

• Exploring different types of insurance

• Learning how to throw darts

What is the first step in solving the problem using fractions?

• Divide the total number of throws by the fraction

• Set up a proportion

• Multiply the fraction by the total number of throws

• Convert the fraction to a percentage

How do you convert a percentage to a decimal?

• Divide by 100

• Multiply by 100

• Add 100

• Subtract 100

Using the percentage method, how many bull's-eyes will Dana make out of 75 throws?
