The answer is a) 1/8. This is because the chance of getting heads is 1/2 because there are 2 sides of a coin, and the chances of getting a red on the spinner is 1/4 because there are 4 choices on the spinner. Therefore, you just multiply 1/2 and 1/4 to get 1/8. Hope this helps!

Here we will apply rule of 3...
This formula, A = πR², its for the whole circle, that is, 360° (2π)
We want the area of only a part, that is, a circular sector whose angle π/6
sector area
2π ----- πR²
π/6 ----- X
2πX = (π/6).πR²
2πX = π²R²/6
X = π²R²/12π
<h3>X = πR²/12</h3>
If Ronisha multiply the area by 1/12 she will get the area of sector with angle of π/6
153.5
Supplementary means add to 180
180- 26.5= 153.5
