Answer:
(a) moment generating function for X is
(b)
Step-by step explanation:
Given X represents the number on die.
The possible outcomes of X are 1, 2, 3, 4, 5, 6.
For a fair die,
(a) Moment generating function can be written as .
(b) Now, find using moment generating function
Hence, (a) moment generating function for X is .
(b)
Answer:
between 4 and 5
Step-by-step explanation:
Step-by-step explanation:
y4 - 2y3 = 0
y3(y - 2) = 0
y3 = 0
y = 0
Y - 2 = 0
Y = 2
