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
