I have a total of 1000 marbles, with 300 red, 600 blue, 100 green.
P(red marble) = 30%
P(blue marble) = 60%
P(green marble) = 10%
If I take a sample of 10 marbles..
What is the probability distribution of red marbles marbles? In other words, what is the expected value of getting 0,1,2,3,4,5,6,7,8,9,10 red marbles in the sample?
I don't need a list of the E(x) of 0-10, but please show work on how to do one or two examples.
