62. A CD has diameter of 120 millimeters. When playing
audio, the angular speed varies to keep the linear
speed constant where the disc is being read. When
reading along the outer edge of the disc, the angular
speed is about 200 RPM (revolutions per minute).
Find the linear speed.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
