Provide an exact evaluation of the expression: tan(7pi/12)
a. -2(1-√3)^-2
b. 2(1+√3)^-2
c. -2(1+√3)^-2
d. 2(1-√3)^-2

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

answer is more than one

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
