A girl speaks the truth 4 out of 5 times. If she throws a
die and reports it to be a 6, What is the probability of it
being a 6?
Answer Posted / k sanghvi
p(a)=the girl speak truth
p(e)=the dies report
p(e/a)=if the girl speak truth tht the die report is 6
p(a)=4/5
p(e/a)=4/5/1/6
so the probabaility
=p(a)*p(e/a)
=4/5*4/5/1/6
=4/5*24/5
=96/5
