Answer:
![-\frac{17}{24}](https://tex.z-dn.net/?f=-%5Cfrac%7B17%7D%7B24%7D)
Step-by-step explanation:
First we need to find the common denominator of 8 and 12, which is 24.
Next we rewrite our fractions:
![-\frac{9}{24} - \frac{8}{24} = -\frac{17}{24}](https://tex.z-dn.net/?f=-%5Cfrac%7B9%7D%7B24%7D%20-%20%5Cfrac%7B8%7D%7B24%7D%20%3D%20-%5Cfrac%7B17%7D%7B24%7D)
This cannot be reduced.
3 H and 1 T l:- number of sequences = 4P3 = 4*3*2*1 / 3*2*1 = 4
Similarly for 3T and 1 H there are also 4
Total = 8 (answer).
The equation of a circle
![(x-xc)^2+(y-yc)^2=r^2](https://tex.z-dn.net/?f=%28x-xc%29%5E2%2B%28y-yc%29%5E2%3Dr%5E2)
defines a circle centred at (xc,yc) with radius r.
So with (xc,yc)=(0,3), and r=4
the equation becomes
![(x-0)^2+(y-3)^2=4^2](https://tex.z-dn.net/?f=%28x-0%29%5E2%2B%28y-3%29%5E2%3D4%5E2)
