[AI-generated answer — Bot GPT 3.5]

The probability of picking an even number first is 4/8 (there are 4 even numbers out of 8 total cards).

Then the probability of picking a 7 is 1/8 (there is only 1 card with a 7 out of 8 total cards).

Therefore, the overall probability is (4/8) * (1/8) = 1/16 or 0.0625.

So, the probability of picking an even number and then picking a 7 is 1/16 or 0.0625.
