E_(1) , E_(2) are events of a sample space such that P(E_(1))=(1)/(4) , P((E_(2))/(E_(1)))=(1)/(2) , P((E_(1))/(E_(2)))=(1)/(4) then P((E_(1))/(E_(2)))+P((E_(1))/(barE_(2)))=
E_(1) , E_(2) are events of a sample space such that P(E_(1))=(1)/(4) , P((E_(2))/(E_(1)))=(1)/(2) , P((E_(1))/(E_(2)))=(1)/(4) then P((barE_(1))/(E_(2)))=
P (E ) +P ( E' )=…….
If E_(1),E_(2) are two events with E_(1)capE_(2)=phi then show that P(E_(1)^(C)capE_(2)^(C))=P(E^(C))-P(E_(2))
An urn contains four balls bearing numbers 1,2,3 and 123 respectively . A ball is drawn at random from the urn. Let E_(p) i = 1,2,3 donote the event that digit i appears on the ball drawn statement 1 : P(E_(1)capE_(2)) = P(E_(1) cap E_(3)) = P(E_(2) cap E_(3)) = (1)/(4) Statement 2 : P_(E_(1)) = P(E_(2)) = P(E_(3)) = (1)/(2)
The two events E_(1), E_(2) are such that P(E_(1)uuE_(2))=5/8, P (bar(E)_(1))=3/4, P(E_(2))=1/2 , then E_(1) and E_(2) are
