Final answer:
The probability of picking a 6 and then picking a 6 without replacement is 1/221.
Step-by-step explanation:
To calculate the probability of picking a 6 and then picking a 6 without putting the first card back, we need to consider that the first card is a 6 and then the second card is a 6.
There are 4 sixes in a standard deck of 52 cards. Since we don't replace the first card, there will be only 3 sixes left in the remaining 51 cards when we pick the second card.
Therefore, the probability of picking a 6 and then picking a 6 is 4/52 * 3/51 = 1/221.
