Part A
P(white) = (3 white)/(10 total) = 3/10
<h3>Answer: 3/10</h3>
==============================================
Part B
10 total, 3 are white
10-3 = 7 are not white so they are either black or red
P(black or red) = 7/10
<h3>Answer: 7/10</h3>
==============================================
Part C
Earlier in part B we calculated 7 beads that weren't white
This means P(not white) = P(black or red) = 7/10
They are the same probability just phrased slightly different ways.
<h3>Answer: 7/10</h3>
==============================================
Part D
There aren't any blue beads (unless there's a typo somewhere). So the probability of picking not blue is 100% or we represent this as the value 1.
<h3>Answer: 1</h3>

Answer: It represents the area of the two circular sides ("lids")
Explanation:
Imagine you made a cylinder out of 3 pieces of paper. The cylinder can be decomposed into two circular shapes (radius r) and one rectangular piece with two side lengths: one is "h", the other has to be long enough to go around each of the disks, so it has to be 2*pi*r long.
So the term 2*pi*r*h is the area of the rectangular piece and pi*r^2 is the area of each of the "lids" Since there are two of those, the term 2*pi*r^2 represents the area of the bottom and top lids.
