For the first letter drawn, there are no conditions/restrictions we need to consider. So, the number of ways to draw an i is:
![\text{Draw(i): } \frac{4}{11}](https://tex.z-dn.net/?f=%5Ctext%7BDraw%28i%29%3A%20%7D%20%5Cfrac%7B4%7D%7B11%7D)
For the second draw, the i is not replaced. That means, we've shrunk the sample space because we're dealing with less elements for the second draw. Firstly, one i disappears since we picked an "i" and there are 10 elements left, not 11.
Thus, to draw the second i, we have:
![\text{Draw(ii): } \frac{3}{10}](https://tex.z-dn.net/?f=%5Ctext%7BDraw%28ii%29%3A%20%7D%20%5Cfrac%7B3%7D%7B10%7D)

Answer:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
Step-by-step explanation:
First calculate the value of the 3 shirts as follows:
$ 71.83 - $ 7.99 = $ 63.84.
$ 63.84.
The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:
x + y + z = 63.84, then for each shirt would be the following equations:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:
<em>z = 63.84 - 20 - 30 = $ 13.84</em>
