1. Alex, 6, Westgate says:

As far as I can see, 1 appears 8 times, 2 appears 12 times, 3 appears 12 times, 4 appears 7 times, 5 appears 8 times, 6 appears 8 times, 7 appears 7 times, 8 appears 11 times, 9 appears 11 times and 0 appears 8 times. The only digit that doesn’t appear in the first 30 places is 0.

2. Jacob H., 4, Westbrook says:

0! I look through and started at 1 and then I made a chart and realized I forgot zero!

3. Evan ,6, Prairie Lane says:

Zero is the right answer because there is no 0 in the first 30 places.

4. Bella says:

0 is not in the first 30 digits

5. Daisyana says:

Zero is not in the first 30 digits
