12 dice were rolled and a 2 occurred 3 times. a) What was the relative frequency of rolling a 2?
b) Using the results of the trial to predict future outcomes, how many times would you expect a 2 to occur if 36 dice are rolled?

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
