Find the range of your data.
The range of the data is the difference between the largest and smallest values.
Largest value: 384
Smallest value: 22
Range = 384 - 22 = 362
Therefore, the range of the data set is 362.
A single standard number is tossed. What is the probability of getting a number greater than 3?
There is only one standard die, which has six sides numbered 1 through 6. The probability of getting a number greater than 3 is the probability of rolling a 4, 5, or 6, which are three of the six possible outcomes. Therefore, the probability of getting a number greater than 3 is:
3/6 or 1/2
This can also be expressed as a decimal or percentage:
0.5 or 50%
To find the range of the given data set, you need to determine the difference between the largest and smallest values.
Step 1: Identify the largest value in the data set.
In this case, the largest value is 384 (pages in book 2 and book 5).
Step 2: Identify the smallest value in the data set.
The smallest value is 22 (pages in book 9).
Step 3: Find the difference between the largest and smallest values.
Subtract the smallest value (22) from the largest value (384):
384 - 22 = 362
So, the range of the data set is 362.
