1 Two Friends Geeta and Sita were playing near the river. So, they decide to play a game in which they have to throw the stone in the river, and whoever will throw the stone at maximum distance, win the game. Geeta Starts first and throws the stone in the river. During her throw, her hand was making an angle of 60° with the Horizontal plane. Sita throws at 45°.
(a) The shape of trajectory formed by stone when Geeta & Sita throw it in the river, is:
- Straight Line
- Semi circle
(b) If we make a mathematical equation of the path followed by stone when Geeta & Sita threw it in the river, then the resulting mathematical equation would be:
(c) Let there be a Polynomial y=2x2-3x+1, then the curve formed by this Polynomial would be:

(b) The probability that the fallen coin will be 5 rupees coin, is---------
(c) The probability that the fallen coin will be 2 rupees coin, is---------
(d) The probability that the fallen coin will be 2 rupees coin or 5 rupees coin, is--------
