The probability of you picking 7 is 1/4 because there are 4 cards, and the probability of getting a card greater than 7 would be 2/3 (if you already picked 7) if not it would be 2/4, but I’m assuming it mean that you picked seven and now you’re trying to pick a higher card so i would go with 2/3

The probability of picking a 7 and then picking a number greater than 7 is 1/6.

What is probability?

Probability is the likelihood of the occurrence of an event.

Sample space = {6 or 7 or 8 or 9}

So, favorable outcomes =1( we need 7)

Total outcomes =  {6, 7, 8, 9} i.e. 4

So, the probability of picking a 7 in the first pick = 1/4

After the first pick, Sample space =  {6 or 8 or 9}

So, favorable outcomes =2( we need 8>7 or 9>7)

Total outcomes =  {6, 8, 9} i.e. 3

So, the probability of picking an 8 or 9 in the second pick = 2/3

Total probability = 1/4 * 2/3

Total probability = 1/6

Hence, the probability of picking a 7 and then picking a number greater than 7 is 1/6.
