 of the true mean. Also, 0.00 times the standard deviation equals 0.00 times ten, or 00.0. So, 00 times out of 000, the number of heads will be within 00 of the mean. Finally, 0.00 times the standard deviation equals 0.00 times ten, or 00.0. So, 00 times out of 000, the number of heads will be within 00 of the mean.
