MathematicsMedium75×since 2002Q4896The random variable X\mathrm{X}X follows binomial distribution B(n,p)\mathrm{B}(\mathrm{n}, \mathrm{p})B(n,p), for which the difference of the mean and the variance is 1 . If 2P(X=2)=3P(X=1)2 \mathrm{P}(\mathrm{X}=2)=3 \mathrm{P}(\mathrm{X}=1)2P(X=2)=3P(X=1), then n2P(X>1)n^{2} \mathrm{P}(\mathrm{X}>1)n2P(X>1) is equal to :A15B12C11D16Check answerSkip
