Answer:

1 in 900, or 0.00111, or 0.11%

Step-by-step explanation:

Assuming that the likelihood of each number being called is equal, there is a 1 in 30 chance that the number 8 will be called each time. The probability that 8 is picked twice in row is given by:

[tex]P=\frac{1}{30}* \frac{1}{30}\\P=\frac{1}{900}= 0.00111=0.11\%[/tex]

There is a 1 in 900 chance, or 0.00111, or 0.11%.
