For
reading the fraction like f(x)/h only (f(x+h) start fraction f(x) / h end fraction), the answer is 
Divide the top and bottom by 2.
14 / 2 = 7
16 / 2 = 8
7/8
Answer:
a) P ( 3 ≤X≤ 5 ) = 0.02619
b) E(X) = 1
Step-by-step explanation:
Given:
- The CDF of a random variable X = { 0 , 1 , 2 , 3 , .... } is given as:
Find:
a.Calculate the probability that 3 ≤X≤ 5
b) Find the expected value of X, E(X), using the fact that. (Hint: You will have to evaluate an infinite sum, but that will be easy to do if you notice that
Solution:
- The CDF gives the probability of (X < x) for any value of x. So to compute the P ( 3 ≤X≤ 5 ) we will set the limits.

- The Expected Value can be determined by sum to infinity of CDF:
E(X) = Σ ( 1 - F(X) )

E(X) = Limit n->∞ [1 - 1 / ( n + 2 ) ]
E(X) = 1
Answer:%28a-b%29%2Fb=c
a-b=bc
a=bc%2Bb
a=b%28c%2B1%29
a%2F%28c%2B1%29=b
b=a%2F%28c%2B1%29
So the answer is b=a%2F%28c%2B1%29
