Number of times to land on U
First, calculate the theoretical probability of U
![Pr(U) = (U)/(Spinner)](https://img.qammunity.org/2022/formulas/mathematics/high-school/x9apniwtkwmpb9abstdwe9bkhnpx3ri3yt.png)
![Pr(U) = (1)/(10)](https://img.qammunity.org/2022/formulas/mathematics/high-school/laz0xccmd5wcc3p961zowka3tu2yr27vcw.png)
The expected number (E) of time to land on U is then calculated as:
![E = Pr(U) * n](https://img.qammunity.org/2022/formulas/mathematics/high-school/kveb358mh0z5ocdzt07w4kdd5i8btwxyre.png)
![E = (1)/(10) * 75](https://img.qammunity.org/2022/formulas/mathematics/high-school/b6rxktxhdxuiwgmsyyla1y8en2kn4n3vtn.png)
![E = 0.10 * 75](https://img.qammunity.org/2022/formulas/mathematics/high-school/fbpfqycuvdwk024ij644y4e0k7yp8d13zc.png)
![E = 7.5](https://img.qammunity.org/2022/formulas/mathematics/high-school/qb5706vwv8ttkoltyinndxeswj7y8ybsli.png)
Approximate
