Standard normal distribution {Ans: has a mean of 0 and variance of 1.}When events are disjoint {Ans: P(A|B)=0 P(B|A)=0}dbinom(j,n,p) {Ans: R code for binomial experiment where P(X)=j}the distribution is normal {Ans: If the sample mean is normal}dim() {Ans: Check how big a set is in R}pbinom(j,n,p) {Ans: R code for binomial experiment where P(X)<=j}
