Using the discrete distribution, it is found that the probability that it offers an even number of honors classes is of 0.68.

<h3>What is the discrete probability distribution?</h3>

The distribution for the number of honors classes the school offers is given by:

  • P(X = 0) = 0.38
  • P(X = 1) = 0.12.
  • P(X = 2) = 0.25.
  • P(X = 3) = 0.2.
  • P(X = 4) = 0.05.

Hence the probability of an even number is given by:

P(even) = P(X = 0) + P(X = 2) + P(X = 4) = 0.38 + 0.25 + 0.05 = 0.68.
