Use the probability distribution to complete parts (a) through (d) below.
The probability distribution of number of televisions per household in a small town
\[
\begin{array}{lcccc}
\mathbf{x} & 0 & 1 & 2 & 3 \\
\mathbf{P}(\mathbf{x}) & 0.02 & 0.16 & 0.25 & 0.57
\end{array}
\]
(a) Find the probability of randomly selecting a household that has one or two televisions.
The probability is

Step 1 ：The probability distribution of the number of televisions per household in a small town is given as follows: \[\begin{array}{lcccc} \mathbf{x} & 0 & 1 & 2 & 3 \\ \mathbf{P}(\mathbf{x}) & 0.02 & 0.16 & 0.25 & 0.57 \end{array}\]

Step 2 ：We are asked to find the probability of randomly selecting a household that has one or two televisions.

Step 3 ：To do this, we need to add the probabilities of selecting a household with one television and the probability of selecting a household with two televisions.

Step 4 ：The probability of selecting a household with one television is 0.16 and the probability of selecting a household with two televisions is 0.25.

Step 5 ：Adding these two probabilities together gives us a total probability of 0.41.

Step 6 ：Final Answer: The probability of randomly selecting a household that has one or two televisions is \(\boxed{0.41}\).
