Sagot :

To determine the probability that a randomly selected house with 2 bathrooms has 3 bedrooms, we will follow these steps:

1. Identify the number of houses with 2 bathrooms and 3 bedrooms:

From the table, we can see that there are 24 houses with 2 bathrooms and 3 bedrooms.

2. Identify the total number of houses with 2 bathrooms:

From the table, we can see that the total number of houses with 2 bathrooms is 30.

3. Calculate the probability:

The probability is given by the number of houses with 2 bathrooms and 3 bedrooms divided by the total number of houses with 2 bathrooms.

So, the probability is:
[tex]\[ \text{Probability} = \frac{\text{Number of houses with 2 bathrooms and 3 bedrooms}}{\text{Total number of houses with 2 bathrooms}} \][/tex]

Substituting in the values from the table we get:
[tex]\[ \text{Probability} = \frac{24}{30} = 0.8 \][/tex]

Therefore, the probability that a randomly selected house with 2 bathrooms has 3 bedrooms is [tex]\(0.8\)[/tex]. The answer is:

[tex]\[0.8\][/tex]
