If Xis a random variate following binomial distribution with mean 2.4 and variance 1.44, Find
P(X? 5)​

Answer 1

Mean = 2.4
np = 2.4.......,,(1)

Variance = 1.44
npq = 1.44
2.4 q = 1.44
q = 1.44/2.4 = 0.6

As we know, p + q = 1
p = 1 - 0.6 = 0.4

Now, from (1)
np = 2.4
0.4 n = 2.4
n = 6

Now what to find is missing,.....,
Hope it helps u.....
