If a cylinder has a height of 10 cm and radius of 5 cm, then if it is tossed, then what is the probability that, it's plane round surface will fall facing the ground

Re: Cylinder probability
Total surface area of the cylinder=$2\pi r(r+h)$=$2\pi \times 5(5+10)=500\pi$
Area of the plane round surface=$2\pi r^2$=$2\pi 5^2$=$50\pi$
Probability=$\frac{500\pi}{50\pi}$=$10$
Area of the plane round surface=$2\pi r^2$=$2\pi 5^2$=$50\pi$
