Answer: The probability that the arrow will point to blue is more than 1/3.
Reason: From the description blue is almost 1/2, red is a little more than 1/4, green a little less than 1/4, and yellow about 1/8. So blue (≈0.45–0.5) is certainly greater than 1/3 (≈0.33). The other statements are false: yellow ≠ red, green ≠ 1/4, and blue is not exactly 1/2.
