Ananya closely followed the basketball career of Diana Taurasi, a legendary 3-point shooter. Mesmerized by Taurasi’s precision, Ananya embarked on a statistical exploration, revealing that each time Taurasi aimed for a 3-point shot (Success yields 3 points; failure yields 0.), she possessed a 37% chance of success, irrespective of her prior attempts. Curious about the outcome, Ananya sought to uncover the variance in the total number of points scored by Taurasi given, that she takes seven 3-point shots during a gripping game.
