While it is possible to estimate the probability of including a sample unit in a probability sample, it is often difficult to do so precisely. This is due to factors such as sampling frames that may not be complete or accurate, or respondents who refuse to participate in the survey. Therefore, while probabilistic methods can be used to estimate the probability of inclusion, it may not be possible to do so with a high degree of accuracy. However, as long as probabilistic methods are used to select the sample, the sample can still be considered a probability sample.
