Give the probability that the spinner shown would land on (a) red, (b) yellow, and (c) blue. Assume all sectors of the spinner are the same size.

Step 1 ：Assume a spinner with 3 sectors: red, yellow, and blue. Since all sectors are the same size, the probability of landing on any one color is equal.

Step 2 ：Calculate the probability using the formula: probability = number of favorable outcomes / total number of outcomes. In this case, the number of favorable outcomes is 1 (landing on a specific color) and the total number of outcomes is 3 (the number of sectors).

Step 3 ：Substitute the values into the formula: probability = 1 / 3 = 0.3333333333333333

Step 4 ：Final Answer: The probability that the spinner would land on red, yellow, or blue is \(\boxed{0.33}\) or \(\boxed{\frac{1}{3}}\).
