A roulette wheel has 37 numbers (0 through 36).

1 answer:

5 0

$\large\boxed{\frac{1}{1369}}$

We'll assume that there is an equal probability of any position on the wheel, so a $\frac{1}{37}$ chance for any given number.

We must take the probability of getting a 27, then the probability of getting a 15, and multiply them together to find the chances that they both happen in a row.

$\frac{1}{37}\cdot\frac{1}{37}=\boxed{\frac{1}{1369}}$
