Answer 1

To find the probability that someone's favorite activity is sleeping, we first note the total number of respondents and the activities they favored.

Out of 150 respondents:
- 30 favored building a snowman
- 80 liked skiing
- 40 preferred sledding

To determine the number of respondents who didn't favor any of these listed activities, we sum the number of respondents who favored the specified activities:

\[
30 + 80 + 40 = 150
\]

Since all 150 respondents selected one of the activities listed, it implies that no respondents mentioned sleeping as their favorite activity.

Given that 0 respondents favored sleeping, the probability of selecting someone whose favorite activity is sleeping is:

\[
\text{Probability} = \frac{\text{Number of respondents who favor sleeping}}{\text{Total number of respondents}} = \frac{0}{150} = 0
\]

Therefore, the experimental probability that someone's favorite activity is sleeping is:

\[
\boxed{0}
\]
