The random variable X follows binomial distribution B(n, p), for which the difference of the mean and the variance is 1.
If 2 P(X = 2) = 3 P(X = 1), then n 2 P(X > l) is equal to
Text Solution
Verified by ExpertsThe correct answer is:
B
Given that the difference between the mean and variance is 1.
np - npq = 1
np(1 - g) = 1
np 2 = 1
Also given that,
2P(X = 2) = 3P(X = 1)
Now,
Hence this is the correct option.
