Answer:
[tex]\text{ D: 75}[/tex]Explanation:
Here, we want to get the number of times it is expected that the spinner lands on 1
Let us have the size of each of sections 3,4,5 as x
Now, the size of section 2 is twice as large 3,4,5: so we have it as 2 * x = 2x
The size of 1 is 3 times 3,4,5 which is 3 * x = 3x
The sum of all these is 360 degrees
Thus, we have it as:
[tex]\begin{gathered} \text{ x + x + x + 2x + 3x = 200} \\ 8x\text{ = 200} \\ x\text{ = }\frac{200}{8}=\text{ 25} \end{gathered}[/tex]But:
[tex]\text{ sector 1 is 25 }\times\text{ 3 = 75}[/tex]
