Step-by-step explanation:
Remove the unnecessary parentheses
Add the numbers: 1 and 9
Hope I helped!
Best regards! :D
I’m not sure but one of the numbers could be 1 and the other could be 0.5. These are possible answers that could go in the boxes. I got this because I knew that I had to get a number that’s less than 10. So when you do 8+1 you get 9 which is less than 10. I picked 0.5 because it said in the question we can’t pick the same number so I picked a decimal. When you do 8+0.5 you get 8.5 which is less than 10.
Hope this helped

Step-by-step explanation:
Sorry but there's know question.
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
