To calculate the experimental probability of seeing a vulture based on Nate's observations, you use the formula for experimental probability:
\[ P(\text{vulture}) = \frac{\text{Number of vultures seen}}{\text{Total number of birds seen}} \]
Given that Nate has seen 2 vultures out of a total of 12 birds, the probability can be calculated as follows:
\[ P(\text{vulture}) = \frac{2}{12} = \frac{1}{6} \]
Thus, the experimental probability that the next bird Nate sees will be a vulture is:
\[ P(\text{vulture}) = \frac{1}{6} \]
