Question
A service station has both self-service and full-service islands. On each island, there is a single regular unleaded pump with two hoses. Let \( X \) denote the number of hoses being used on the self-service island at a particular time, and let \( Y \) denote the number of hoses on the full-service island in use at that time. The joint pmf of \( X \) and \( Y \) appears in the accompanying tabulation.

\[
\begin{array}{c|ccc}
p(x,y) & y = 0 & y = 1 & y = 2 \\
\hline
x = 0 & 0.10 & 0.03 & 0.02 \\
x = 1 & 0.07 & 0.20 & 0.07 \\
x = 2 & 0.06 & 0.14 & 0.31 \\
\end{array}
\]

(a) Given that \( X = 1 \), determine the conditional pmf of \( Y \)—i.e., \( P(Y = 0 | X = 1) \), \( P(Y = 1 | X = 1) \), \( P(Y = 2 | X = 1) \). (Round your answers to four decimal places.)

- \( P(Y = 0 | X = 1) \) = [ ]
- \( P(Y = 1 | X = 1) \) = [ ]
- \( P(Y = 2 | X = 1) \) = [ ]

(b) Given that two hoses are in use at the self-service island, what is the conditional pmf of the number of hoses in use on the full-service island? (Round your answers to four decimal places.)

\[
\begin{array}{c|ccc}
y & 0 & 1 & 2 \\
\hline
P(Y = y | X = 2) & & & \\
\end{array}
\]

(c) Use the result of part (b) to calculate the conditional probability \( P(Y \leq 1 | X = 2) \). (Round your answer to four decimal places.)

- \( P(Y \leq 1 | X = 2) \) = [ ]

(d) Given that two hoses are in use at the full-service island, what is the conditional pm
