b. A part prope nonempty ? (ie, A ? ?, A ? ?) and the tribe associated A = {?, A, A ?, ?}. We define the real application Y on ? by: Y (a) = 1 if a?A and Y (a) = 0 otherwise. Show that Y is a random variable Discreet on (?, A). If the probability P is defined on (?, A) P (A) = p where p? ] 0.1 [, calculate P (Y> 2), p_y (0), P (Y <0.5 ) And P (Y = 1 or 2).
the original is in franch but i go to translate it in google translate . so please detail when u solution. Thanks in Advance.
