What is the probability of picking an even number and then picking an even number?
Write your answer as a percentage.
The probability of picking an even number on the first draw is 3/6 (there are 3 even numbers out of 6 total numbers).
After picking the first even number, there are now 5 cards left, with only 2 even numbers. So the probability of picking a second even number is 2/5.
Therefore, the probability of picking an even number and then picking an even number is (3/6) * (2/5) = 6/30 = 1/5 = 20%.
So the probability is 20%.
