Problem – 16

What is the probability that a fair die never comes up an even number when it is rolled ten times?

Solution :

Probability to rolled the die for one time and comes up an even number = $\frac{3}{6}= \frac{1}{2}$

As the rolls are independent so probability after rolling ten times = $\left ( \frac{1}{2} \right )^{10}= \frac{1}{1024}$
