Quizplus · Accepted Answer

The probability of having a demand for at least two microcomputers is the complement of having a demand for fewer than two microcomputers. If the probability of having a demand for fewer than two microcomputers is 0.3, then the probability of having a demand for at least two is 1 - 0.3 = 0.7.
