    Answer:

    0.30

    Step-by-step explanation:

    Find the probability by adding the probabilities together for having two and four honors classes.

    25% offer two honors classes and 5% offer four honors classes. Add these together:

    25 + 5

    = 30

    So, there is a 30% probability that the school offers an even number of honors classes.

    The correct answer is 0.30.
