Answer: 4/5 or 80%
Explanation:
Since the spinner has five equal sections, each numbered 1 through 5, the probability of landing on any particular number is 1/5.
To find the probability of not landing on 4, we need to add up the probabilities of landing on all the other numbers and subtract that sum from 1 (since the sum of all possible outcomes must equal 1).
The probability of landing on 4 is 1/5, so the probability of not landing on 4 is:
1 - 1/5 = 4/5
Therefore, the probability of not landing on 4 is 4/5 or 0.8, which is equivalent to an 80% chance.
