c

Step-by-step explanation:

since all the tangent(tan) angles are multiplying,

you factor tan out and multiply the numbers. that's : tan( 23+35+60+67+55)

tan(240)

tan(240) =√3

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%
