Question 308734: Probability question: a student is taking two courses, history and math. The probability the student will pass the history course is .6, and the probability of passing the math course is .7. The probability of passing both is .5. What is the probability of passing at least on course?
Is this the correct answer?
1-(.3)(.4)(.5)=.94

-----
P(pass at least one) = 1 - P(fail both)
= 1 - (0.4)(0.3)
= 1 - 0.12
- 0.88
