Question

Yesterday late evening, after burning the effigy of Ravana, i returned home and started playing cards with my niece. She said, " i will pick up a card randomly from well shuffled pack of cards and i will tell you what it is. After that you have to pick up a card which has the same number or alphabet on it". She also said i will say truth in 2 occasions out of every 3 occasions. After picking up a card, she said it is number 5. Now, what is the probability that i will get a card with number 5?
