The probability of the arrow not landing on a section labeled with an odd number is 3/7
Step-by-step explanation:
Total number of congruent sections is 7
Total number of congruent sections with odd numbers(1,3,5,7) is 4.
The probability of the spinner landing on a section labelled with an odd number is 4/7.
The probability of the spinner landing on a section which is not labelled with an odd number is 1-4/7 = 3/7 ( Because the sum of probability of the spinner landing on any number is 1)
Hence the answer is 3/7
