A number is chosen at random from 1 to 10. Find the probability of
not selecting 3 or a multiple of 3.

Mutiples of 3 between 1 and 10 include 3,6,9

So the chances are 70% you dont select any of those numbers.

Step-by-step explanation:

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

answer: what are the following choices
