Option 2 -

Step-by-step explanation:

To find : Which formula finds the probability that a point on the grid below will be in the blue area ?

Solution :

Probability is defined as the number of favorable outcome divided by total number of outcome.

As

The probability that a point on the grid below will be in the blue area is given by,

Therefore, option 2 is correct.

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
