Answer 1

Given

Prediction of rain on Saturday 50% Sunday 40%. If these predictions are correct what is the probability it WILL NOT rain over the weekend?

Solution

$Probability\text{ =}\frac{Possible\text{ outcome}}{Total\text{ outcome}}$

Possible outcome

$\begin{gathered} correct\text{ prediction=}50\text{ \% +40 \%=90 \%} \\ Total\text{ outcome =100\%} \end{gathered}$

The probability it WILL NOT rain over the weekend i.e incorrect prediction

$100\text{ \%-90 \%=10\%}$

The final answer

$10\text{ \%}$
