List IList II (A)Let n be a number chosen randomly fromthe set of first 100 natural numbers. Thenthe probability that the value of (1+i)nis real, is (P)2(B)If the coefficient of x13 in the expansion of(1−x)5(1+x+x2+x3)4 is k, then thevalue of k4 is(Q)0.35(C)In an examination of 9 papers, a candidate has to pass in more papers than (s)he fails inorder to be successful. If the number ofways in which (s)he can be unsuccessful is 2m,then the value of m4 is (R)0.55(D)A,B,C are three events such that P(A)=0.6,P(B)=0.4,P(C)=0.5,P(A∪B)=0.8,P(A∩C)=0.3 and P(A∩B∩C)=0.2. If P(A∪B∪C)≥0.85and P(B∩C) lies in the interval [0.2,b],then the value of b is(S)1(T)0.5(U)0.25
