Amit, Sumit and Pramit go to a seaside town to spend a vacation there and on the first day everybody decides to visit different tourist locations. After breakfast, each of them boards a different tourist vehicle from the nearest bus-depot.

Pramit learns from the local guide that at that time of the year, only eight sea - creatures (including a shark) are observable and the probability of observing any creature is equal. However, Amit and Pramit later recall during their discussion that Sumit has a reputation for not telling the truth five out of six times. What is the probability that Sumit actually observed a shark in the waters?

A regular hexagon with a perimeter of 288^(1/2) lies in the Cartesian plane in such a way that it's center is on the origin and the two of it's vertices lie on the X-axis and midpoints of the two sides lie on the Y-axis. If the portion of the hexagon that lies in quadrant I is completely revolved around X-axis, a solid whose volume is X units. If the same portion is revolved around Y-axis, we get a solid of volume Y units. Evaluate (X/Y)^2.
