Question A wheel has 5 slices numbered 1 to 5, some grey and some white. Find $P(X)$, the probability the wheel stops on a white slice, and $P(\text{not }X)$, the probability it stops on a non-white slice.

Studdy Solution
Fill in the probability of event not $X$ in the table.
\begin{tabular}{|c|c|c|c|c|c|c|} \hline \multirow{2}{*}{ Event } & \multicolumn{5}{|c|}{ Outcomes } & \multirow{2}{*}{ Probability } \\ \cline { 2 - 6 } & 1 & 2 & 3 & 4 & 5 & \\ \hlineX & \checkmark & & \checkmark & & & P(X)=\frac{2}{5} \\ \hline not X & & \checkmark & & \checkmark & \checkmark & P(\operatorname{not} X)=\frac{3}{5} \\ \hline \end{tabular}
The probabilities for the events are $P(X) = \frac{2}{5}$ and $P(\text{not } X) = \frac{3}{5}$.
