QuestionThe table gives a set of outcomes and their probabilities. Let AA be the event "the outcome is greater than or equal to 4 ". Let BB be the event "the outcome is greater than or equal to 2 ". Find P(AB)P(A \mid B). \begin{tabular}{|c|c|} \hline Outcome & Probability \\ \hline 1 & 0.2 \\ \hline 2 & 0.2 \\ \hline 3 & 0.3 \\ \hline 4 & 0.3 \\ \hline \end{tabular} \square

Studdy Solution
Use the formula for conditional probability:
P(AB)=P(AB)P(B)=0.30.8=0.375 P(A \mid B) = \frac{P(A \cap B)}{P(B)} = \frac{0.3}{0.8} = 0.375
The conditional probability P(AB) P(A \mid B) is:
0.375 \boxed{0.375}
