Explanation / Answer

If the experiment is done without replacement of cards after viewing, number of cards remaining in the deck = 47

Number of 10's = 4

P(getting a straight 6,7,8,9,10) = 4/47

If the cards are replaced after viewing P(getting a 10) and hence P(getting a straight  6,7,8,9,10) = 4/52 = 1/13
