What is the value of k?
What is the value of k?
Options:
- a) 1 2
- b) 1 3
- c) 1 4
- d) 1 5
- a) 1 2
- b) 1 3
- c) 1 4
- d) 1 5
correct answer : c)
Explanation:
n = 6, p = k Þ q = 1 – k
Now, 9.P(X = 4) = P(X = 2)
9.6C4k4(1 – k)2 = 6C2k2(1 – k)4
9k2 = (1 – k)2 ( 6C4 = 6C2)
3k = 1 – k Þ k = 1
4
n = 6, p = k Þ q = 1 – k
Now, 9.P(X = 4) = P(X = 2)
9.6C4k4(1 – k)2 = 6C2k2(1 – k)4
9k2 = (1 – k)2 ( 6C4 = 6C2)
3k = 1 – k Þ k = 1
