in 'c' part of this question,can you explain how is the probability 2/3 as
it is asking for probability that prize is behind door 1 given that monty has chosen door 2. and you have chosen door 3.
Now,as monty has chosen door 2,definitly it is not the door with the prize,prize can be only in door 1 or door 3,so should'nt it be 1/2??
pleae correct me.
Thankyou
