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:
t - 16
Step-by-step explanation:
Hope this helps!! :))
Answer:
a)
28000 + 3000·x = 36000 + 2000·x --> x = 8 years
b)
28000 + 3000·8 = $52000
Answer:
Obviously only D is true
Note 2 x - 1 < 10 can be rewritten
2 X < 11 and
x < 5.5
So all of the values in the set would have to be less than 5.5
