Example 3.]
1. Let T = {(1, 2), (1, 3), (2, 5), (3, 6), (4, 7)}. T :...
1. Let T = {(1, 2), (1, 3), (2, 5), (3, 6), (4, 7)}. T : X ->
Y. X = {1, 2, 3, 4}, Y = {1, 2, 3, 4, 5, 6, 7}
a) Explain why T is or is not a function.
b) What is the domain of T?
c) What is the range of T?
d) Explain why T is or is not one-to one?

I have a 6 sided die with the numbers 1, 2, 3, 3, 4, 5 on it. I
also have a hat filled with numbers. When I pick a number out of
the hat, I get a number between 1 and 10. The hat number has a mean
of 2 and a standard deviation of 2.5. I make a new random variable
by combining these two previous random variables. The new random
variable is made by taking the number I...
