I was given 3 packets, with 2 pens each.

1st Packet has 2 blue pens.

2nd Packet has 1 blue pen,1 black pen.

3rd Packet has 2 black pens.



I took any one packet and pulled out one pen. It turned out to be a blue
one.

What is the probability that the next pen from the same packet will

also be a blue one?
