I am not a math major, but for a networking class, I am taking I am required to do summations for probability. I know the logic but I don't know the mathematical theory to make this work. Using Wolfram I'm trying to do this
sum [(35 choose n)* (100*j)*(.1^n* .9^(35-n))] from n=0 to 35, if[n>10, j=10, j=n]
Essentially, what I'm asking is: How do I run a summation with a variable that is affected by an
if statement in this way? Or is there a different math I should be using.
Edit: Sorry for not being clear. I am trying to do this in Wolfram Alpha. I did not realize there was a difference.
