Rodrigo chooses a book from the box. The box has 12 science fiction books, 16 mystery books and 12 mythology books. If Rodrigo randomly chooses a book from the box, determine the probability that it will NOT be a science fiction book. Write your answer in the form of a decimal.

28/40

0.7 when you have it as a decimal

Step-by-step explanation:

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
