187. What is the probability that a 6 will not come up in any of the 6 throws of a die?
187. The probability that six points will not fall when a die is rolled once is $\frac{5}{6}$. The probability of not rolling a six in six rolls is given by the formula (6) on page 126

$$
\frac{5}{6} \cdot \frac{5}{6} \cdot \frac{5}{6} \cdot \frac{5}{6} \cdot \frac{5}{6} \cdot \frac{5}{6}=\left(\frac{5}{6}\right)^{6}=\frac{15625}{46656} \approx 0.84
$$
