Question
![(a)
Let X exp(1), and Y = frac(X), the fractional part of X. Compute the
probabiltiy P(Y > 0.5|X ≤ 1.5). Express your answer up to 3rd decimal place. (The
fractional part of a nonnegative number X is defined as frac(X)
X - [X], e.g.,
frac (3232.52) = 0.52, frac(1.232) = 0.232, frac(3) = 0, frac(7): = 0.14159265...)
=
(b)
A point P with coordinates (X, Y) is uniformly chosen from the unit disk
D = {(x, y) : x² + y² ≤ 4}. What is the probability that the maximum of X, Y is
lesser (≤) than 1?](https://content.bartleby.com/qna-images/question/a4f6fb5f-9dce-46e9-a62a-df8f162ca2bd/27d40a0e-2144-4384-ae3c-d96209724298/4w1lgsk_thumbnail.jpeg)
