What is the probability of picking an even number and then picking an even number?
Write your answer as a percentage.
There are 3 even numbers (2, 4, 6) out of the 6 total numbers.
The probability of picking an even number first is 3/6 = 1/2 = 50%
Since we replace the card after picking it, the probability of picking an even number again on the second pick is also 3/6 = 1/2 = 50%
Therefore, the probability of picking an even number and then picking an even number is (1/2) * (1/2) = 1/4 = 25%
So, the probability is 25%.
