The probability of spinning yellow or red is the sum of the individual probabilities of spinning yellow and spinning red.
The probability of spinning yellow is 3 out of 8 parts, or 3/8.
The probability of spinning red is 1 out of 8 parts, or 1/8.
Therefore, the probability of spinning yellow or red is 3/8 + 1/8 = 4/8.
Simplifying, we have 4/8 = 1/2.
Therefore, the probability of spinning yellow or red on this spinner is 1/2.
The correct answer is C) 1/2.
