The seating chart of an airplane shows 30 rows of seats. Each row has 3 seats on each side of the center aisle, and one of the seats on each side is a window saet. The view from the window seats in 10 of the rows is obscured by the wings of the airplane. If the first person to be assigned a seat is assigned a window seat and thw window seat is assigned randomly, what is the probability that the person will get a seat with an unobscured view?  Choose the correct choice from the following
A) 1/6	B) 1/3	C) 2/3	D) 5/6	E) 17/18
priyalr   6 seats per row, think of a boeing 737. We have 30 rows, therefore window 30 seats one one side and 30 window seats on the other, totaling 60 window seats on the whole plane.   the view of the window of 10 rows is blocked. two wings, therefore 20 window seats are blocked.   Total window seats = 60   Total blocked window seats = 20   Total unblocked seats = 40   We know that a window seat was given, therefore probability for not window seat is 40/60 =2/3   ANS 2/3
