To solve this, we typically calculate the probability of the opposite event (no students coming) and subtract it from 1. Without specific details on the initial probability, assuming the question implies a high likelihood of at least one student attending (e.g., based on past patterns or statistical likelihood), the closest to certainty (without being certain) is 0.90. This approach aligns with common probability solving techniques where direct calculation is challenging.
