1.The coefficients a,b,ca, b, ca,b,c in the quadratic equation ax2+bx+c=0ax^2 + bx + c = 0ax2+bx+c=0 are chosen from the set {1,2,3,4,5,6,7,8}\{1, 2, 3, 4, 5, 6, 7, 8\}{1,2,3,4,5,6,7,8}. The probability of this equation having repeated roots is:a.1128\dfrac{1}{128}1281b.164\dfrac{1}{64}641c.3256\dfrac{3}{256}2563d.3128\dfrac{3}{128}1283Login to continueOnly logged in users canattempt or see the solution.
