If?p?and?q?are chosen randomly with replacement from the set {1, 2, 3, 4, 5, 6}, then the probability that the roots of the equation?x2+px+2q=0?are real is .In the solution it is written that the probability of the roots of the equation are real = 1- the probability of being non-real. It is written that they become non-real iff p - 8q
