Probability of Selecting at Least One Red Plant

A researcher is studying a rare species of flower that exists only in a specific region. In one season, the researcher identifies that there are 80 flowering plants in total. Among these, 20 are red, 30 are blue, and 30 are yellow. The researcher decides to randomly select 3 plants without replacement to study their genetic traits.

What is the probability that at least one of the selected plants is red?
