Use the double angle identity:

$\sin^2\dfrac\pi{12}=\dfrac{1-\cos\frac\pi6}2$

Then $\cos\dfrac\pi6=\dfrac{\sqrt3}2$ , so you get

Step-by-step explanation:

The model has three options, each one of which you can either take or not take.

Let us represent taking an option with 1 and not taking an option with 0

1. 0 0 0 ( taking none of the options)

2. 0 0 1

3. 0 1 0

4. 0 1 1

5. 1 0 0

6. 1 0 1

7. 1 1 0

8. 1 1 1 ( taking all three options)

8*4= 32

Hence the largest number of cars having same options and colors is

100,000/32
