Intuitively, one would think the ball would land in the green spot 2 out of the 38 times, since there are 38 slots and 2 are green.

The probability that it lands in a green section is 2/38.  Multiplying this by the number of times the experiment is performed, we get (2/38)(38) = 2.

$3.00 marked up 72%<br><br>(please show your work!!)<br><br>thank you❤️❤️​

<h3>Answer:  $5.16</h3>

==================================================

Work Shown:

72% = 72/100 = 0.72

72% of $3.00 = 0.72*3.00 = 2.16

The price increases by $2.16 to get the final answer of 3.00+2.16 = 5.16 dollars

-------

We can find this answer through this alternative route:

1.72*3 = 5.16

The multiplier 1.72 represents an increase of 72% since 1.72 = 1 + 0.72 = 100% + 72% = 172%
