Question

Giving a test to a group of students, the grades and gender are summarized below \begin{tabular}{|l|l|l|l|l|} \hline A & B & C & Total \\ \hline Male & 6 & 4 & 8 & 18 \\ \hline Female & 10 & 9 & 16 & 35 \\ \hline Total & 16 & 13 & 24 & 53 \\ \hline \end{tabular} Let Y be the event that the student got a "B" If one student is chosen at random, find $P(\overline{Y})$. Hint Remember, the notation $\overline{Y}$ is the 'complement' of event Y. So to find $P(\overline{Y})$, you are finding the probability that event Y did NOT happen. $P(\overline{Y}) = $

Let Y be the event that the student got a "B"
If one student is chosen at random, find $P(\overline{Y})$.
Hint Remember, the notation $\overline{Y}$ is the 'complement' of event Y. So to find $P(\overline{Y})$, you are finding the
probability that event Y did NOT happen.
$P(\overline{Y}) = $

A B C Total

Male 6 4 8 18

Female 10 9 16 35

Total 16 13 24 53

Let Y be the event that the student got a "B"
If one student is chosen at random, find P(Y).
