Let `C_(1) and C_(2)` be two biased coins such that the probabilities of getting heat in a single toss are `(2)/(3) and (1)/(3)`, respectively. Suppose `alpha` is the number of hed that appear when `C_(1)` is tossed twice. Independently. Then the probability that the roots of the quadratic polynomil `x^(2)-ax+beta` are real equals, is
