Go to my most recent question and only answer if you know it.

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%

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
