Answer: 3/4
Explanation:
The probability that you will land on either red or blue is equal to the sum of the probability that you will land on red and the probability you will land on blue.
The probability you will land on red is 1/2 and the probability that you will land on red is 1/4 by the image.
Therefore, the probability you will land on either is 1/4 + 1/2 = 3/4
