\[
\begin{array}{lcc|c|c}
\mathbf{x} & 0 & 1 & 2 & 3 \\
\mathrm{P}(\mathbf{x}) & 0.05 & 0.18 & 0.31 & 0.46
\end{array}
\]
(a) Find the probability of randomly selecting a household that has one or two televisions.
The probability is 0.49
(Type an integer or a decimal. Eio not round.)
(b) Find the probability of randomly selecting a household that has two or more televisions.
The probability is
(Type an integer or a decimal. Do not round.)
Answer
Final Answer: The probability of randomly selecting a household that has one or two televisions is \(\boxed{0.49}\).
Step 1 ：The question asks for the probability of randomly selecting a household that has one or two televisions. This can be found by adding the probabilities of a household having one television and a household having two televisions.
Step 2 ：The probability of a household having one television is \(0.18\) and the probability of a household having two televisions is \(0.31\).
Step 3 ：Therefore, the probability of a household having one or two televisions is \(0.18 + 0.31 = 0.49\).
Step 4 ：Final Answer: The probability of randomly selecting a household that has one or two televisions is \(\boxed{0.49}\).
