The first ten odd prime numbers are: 3, 5, 7, 11, 13, 17, 19, 23, 29, 31
To calculate the mean of the first ten odd prime numbers, we sum them and divide by 10:
Mean = (3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 + 31) / 10 = 158 / 10 = 15.8
Therefore, the mean of the first ten odd prime numbers is 15.8
