area of coin = pie * 1^2 = n(e) area of square= 2^2 * 4(as there are four such squares)= n(S)
probablility = n(E)/n(S) = pie/16 ..... the ans ;) On Fri, Aug 19, 2011 at 10:20 PM, priya ramesh < [email protected]> wrote: > A 1 inch diameter coin is thrown on a table covered with a grid of lines > two inches apart.
