Probability that a student will succeed in I.I.T. Entrance test is 0.2 and that he will succeed in Roorkee entrance test is 0.5. If the probability that he will be successful at both the places is 0.3, then the probability that he does not succeed at both the places, is

Let a_m (m = 1, 2, ,p) be the possible integral values of a for which the graphs of f(x) =ax^2+2bx +b and g(x) =5x^2-3bx-a meets at some point for all real values of b Let t_r = prod_(m=1)^p(r-a_m ) and S_n =sum_(r=1)^n t_r. n in N The minimum possible value of a is
