The probability of the arrow will land on a section labeled with the number greater than 3 is 
Step-by-step explanation:
Given,
The spinner is divided into 8 sections say named 1, 2, 3, 4, 5, 6, 7, 8
To find the P : probability of the arrow will land on a section labeled with the number greater than 3
Formula
<u>P = (the number of possible outcomes) ÷ ( the number of total result)</u>
We will count the probability when the arrow land on either 4 or 5 or 6 or 7 or 8 = 5 times
Total number of result = 8
Hence the probability = 
Step-by-step explanation:
6-20/3=14/3..........
