Statement-I: Under some condition in the random experiment, p and q are the probability of 'success' and probability of 'failure' respectively, then the probability for x success is `f(x)=^nC_xp^xq^(n-x)(x=0,1,2,......,n)` Statement-II: Sample space of a random experiment has only two sample points one is success and other is failure.
A
Statement I is True, Statement II is True, Statement II is a correct explanation for Statement I
B
Statement I is True, Statement II is True, Statement II is not a correct explanation for Statement I

Each question has four choice: a, b, c and d, out of which only one is correct. Each question contains Statement 1 and Statement 2. Find the correct answer. Both the Statements are true but Statement 2 is the correct explanation of Statement 1. Both the Statement are True but Statement 2 is not the correct explanation of Statement 1. Statement 1 is True and Statement 2 is False. Statement 1 is False and Statement 2 is True Statement 1: The lines (a+b)x+(a-2b)y=a are con-current at the point (2/3,1/3)dot Statement 2: The lines x+y-1=0 and x-2y=0 intersect at the point (2/3,1/3)dot
