The probability of passing at least one course can be calculated using the formula: P(passing at least one course) = P(passing history) + P(passing math) - P(passing both) Plugging in the given probabilities, we get: P(passing at least one course) = 0.75 + 0.65 - 0.5 P(passing at least one course) = 0.9 Therefore, the probability of passing at least one course is 0.9, or 90%. This means that the student is very likely to pass at least one of their courses.
