If you roll a 6-sided die 6 times, what is the best prediction possible for the number of times you will roll an even number?

The best prediction possible for the number of times you will roll an even number is 3 times. This is because each roll of the die is independent of the others, and the probability of rolling an even number on any given roll is 1/2. Therefore, the expected value for the number of even rolls in 6 rolls is (1/2) x 6 = 3.
