Possible outcome
![\begin{gathered} correct\text{ prediction=}50\text{ \% +40 \%=90 \%} \\ Total\text{ outcome =100\%} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/xpb7clw9c0zqfmgqdlbmkdruw8ridljzx5.png)
The probability it WILL NOT rain over the weekend i.e incorrect prediction
![100\text{ \%-90 \%=10\%}](https://img.qammunity.org/2023/formulas/mathematics/college/6xgaws2q5xqzd1eqyawu1ny6t6g41o7g3e.png)
