question: A spinner is made with red and blue sections. The desired probability for RED is 0.75. What angle measure is required for the BLUE section.
Hi, I saw these qs in my practice questions and that's how I answered them.
as we have 100-75=25 25% of the circle would be 90 degrees The angle measure for blue would be 90. I'm not sure if that how should do it because my answer looks so basic. I would appreciate it if you tell me that I have answered it right.
Your answer looks correct. The only way that answer would be wrong is if there are, say, 8 total sections of equal size. In such a case we would have 2 blue sections and they would be 45 degrees each. Otherwise, I see no issue with your solution.
