Answer:

-20, -40, -80

Step-by-step explanation:

as we see in the whole number (aka positive number) area, its counting by twenties because it goes from 0-20. since were in the negative area we would want to count up backwards,

so, 0 minus 20 equals -20

-20 minus -20 equals -40

and -20 minus -60 equals -80

hope this helped! <3

Suppose that Y takes on the values {0, 1, 2, 3}, each with probability 1/4. Take a random sample of 5 numbers from this distribu

Answer:

The total number of samples that give this outcome is 5.

Step-by-step explanation:

Since Y takes values in {0,1,2,3}, For us to have that $Y_1+Y_2+Y_3+Y_4+Y_5=1$ implies that all of them are zero but one. The one that is non-zero necessarily is equal to 1. To calculate the number of samples that give this outcome is equivalent to counting the total number of ways in which we can pick the i-index such that $Y_i=1$ . Note that in this case we can either choose Y1 to be 1, Y2 to be 1 and so on. So, the total number of samples that give this outcome is 5.
