Joshua’s calculator is set to generate the numbers from 1 to 10 at random. He notices that out of the 50 numbers his calculator has generated, the numbers 3, 6, and 7 each occurred 9 times. What is the relative frequency of the numbers other than 3, 6, or 7?
how many were not 3,6,7? 50-9 = 41
so, 41/50
To find the relative frequency of the numbers other than 3, 6, or 7, we need to calculate the total number of occurrences of those numbers and divide it by the total number of generated numbers.
First, let's find the total number of occurrences of the numbers other than 3, 6, or 7.
Out of the 50 numbers generated, the numbers 3, 6, and 7 each occurred 9 times. So, the total number of occurrences of these three numbers is 9 + 9 + 9 = 27.
To find the total number of occurrences of the numbers other than 3, 6, or 7, we subtract the number of occurrences of these three numbers from the total number of generated numbers: 50 - 27 = 23.
Now, let's calculate the relative frequency of the numbers other than 3, 6, or 7.
Relative frequency = (Number of occurrences of numbers other than 3, 6, or 7) / (Total number of generated numbers)
Relative frequency = 23 / 50
Simplifying the fraction, we get:
Relative frequency = 0.46
Therefore, the relative frequency of the numbers other than 3, 6, or 7 is 0.46 or 46%.
To find the relative frequency of the numbers other than 3, 6, or 7, first, we need to find the total number of numbers generated by the calculator that are neither 3, 6, nor 7. Let's calculate that:
Total number of numbers generated = total number of occurrences of 3 + total number of occurrences of 6 + total number of occurrences of 7
= 9 + 9 + 9
= 27
Since the calculator has generated a total of 50 numbers, we can find the number of numbers other than 3, 6, or 7 by subtracting the total number of occurrences of 3, 6, and 7 from the total number of numbers generated:
Number of numbers other than 3, 6, or 7 = total number of numbers generated - total number of occurrences of 3 - total number of occurrences of 6 - total number of occurrences of 7
= 50 - 9 - 9 - 9
= 23
Finally, to find the relative frequency of the numbers other than 3, 6, or 7, divide the number of numbers other than 3, 6, or 7 by the total number of numbers generated:
Relative frequency = Number of numbers other than 3, 6, or 7 / Total number of numbers generated
= 23 / 50
= 0.46
Therefore, the relative frequency of the numbers other than 3, 6, or 7 is 0.46 or 46%.
