Lesson Worksheet: Experimental Probability Mathematics
In this worksheet, we will practice interpreting a data set by finding and evaluating the experimental probability.
A light bulb manufacturer examined a sample of 1,000 light bulbs from their production. Using the table which shows the results for this sample, calculate the experimental probability that a light bulb fails after less than 150 hours of use.
|(Hours of Use)|
|Number of Lamps||150||320||270||260|
The table shows the music preferences of a group of men and women.
Calculate the relative frequency of a randomly selected person being a woman who prefers country music. If necessary, round your answer to 3 decimal places.
Calculate the relative frequency of a randomly selected woman preferring rock music. If necessary, round your answer to 3 decimal places.
