D) x=2 y =-4 -4=2-4 -4=-2 false
There's one piece of information missing from the question, so
in order to completely calculate the answer, we must assume the
missing number.
We have no information that helps us calculate the probability
that you will eat the first jelly bean. So we'll have to assume that
you will definitely eat it, no matter what color it is. The probability is 1 .
-- You start out with (2 + 4 + 8 + 6) = 20 jelly beans in the package.
8 of them are purple.
-- If you close your eyes and pull one out of the package, then the
probability that it will be purple is
8 / 20 .
-- You definitely eat it. The probability of this event is 1 .
-- Now there are 19 jelly beans left in the package.
6 of them are blue.
-- The probability of picking a blue one out of the package without peaking is
6 / 19 .
-- The probability of all three of these events happening is
(8/20) · (1) · (6/19)
= (8 · 1 · 6) / (20 ·19)
= 48 / 380
= 12/95 = 0.1263... = 12.63...% (rounded)

Answer: 79 full rotations</h3>
====================================================
Explanation:
150 cm = 150/100 = 1.5 m
The wheel has a diameter of 1.5 meters
The circumference of the wheel is
C = pi*d
C = pi*1.5
C = 1.5pi
C = 4.71238898038469
I'm using my calculator's stored version of pi to get the most accuracy.
Then we divide the 376.8 over the circumference found
(376.8)/(4.71238898038469) = 79.9594434093682
Despite being very close to 80, we must round down to 79 because we don't have enough to get that full 80th rotation. In other words, we have 79 full rotations and then some change leftover.
Though for the sake of simplicity, I can see how it's useful to say "about 80 rotations" if 79 seems a bit clunky. I'll stick with 79 however. Let me know if your teacher instructs otherwise.
