Question
There is a square board of side ‘2a’ units circumscribing a red circle. Jayadev is asked tokeep a dot on the above said board. The probability that he keeps the dot on the shadedregion is
Solution 1
The problem seems to be incomplete as there is no information or diagram provided about the shaded region. However, I can tell you how to approach this problem if we assume the shaded region is the circle.
-
First, calculate the area of the square board. Since the side of the square is '2a', the area of the square (A_square) would be (2a)^2 = 4a^2.
-
Next, calculate the area of the circle. The diameter of the circle is equal to the side of the square, which is '2a'. So, the radius of the circle (r) is 'a'. The area of a circle (A_circle) is given by the formula πr^2. So, the area of the circle is πa^2.
-
The probability that Jayadev keeps the dot on the shaded region (the circle) is the ratio of the area of the circle to the area of the square. So, P = A_circle / A_square = πa^2 / 4a^2.
-
Simplify the equation to find the probability. The 'a^2' terms cancel out, leaving P = π / 4.
So, if the shaded region is the circle, the probability that Jayadev keeps the dot on the shaded region is π / 4.
