The probability of rolling an odd number is 1/2. If you roll a die 500 times, about how many times would you expect to roll an odd number?

You would expect to roll an odd number about 250 times out of the 500 rolls. This is because the probability of rolling an odd number is 1/2, which is equivalent to 50%. Therefore, half of the 500 rolls would result in an odd number, which is 250 times.
