(a)
By the property of Bernoulli Distribution:
Variance of Bernoulli Distribution is given by:
V(X) = p(1-p)
Given:
V(X) = 0.24
Thus, we get:
p (1 - p) = 0.24
i.e.,
p2 - p + 0.24 = 0
So,
Given:
p > 0.5.
So, take positive sign.
We get:
So,
Answer is:
0.6
(b)
By Propertyof Bernoulli Distribution:
E(X) = p
Thus, we get:
E(X) = p = 0.6
So,
Answer is:
0.6
1 ± V1 _ (4 × 0.24) 1 ± 0.2
1.2 p=-=0.0
