Answer:
[tex]\dfrac{1}{1296}[/tex]
Step-by-step explanation:
When a fair die is tossed once, there are 6 possible outcomes: 1, 2, 3, 4, 5, 6.
The probability of rolling 5 is [tex]\dfrac{1}{6}.[/tex]
When a fair die is tossed four times, the probability of rolling 5 all four times is
[tex]\dfrac{1}{6}\cdot \dfrac{1}{6}\cdot \dfrac{1}{6}\cdot \dfrac{1}{6}=\dfrac{1}{6^4}= \dfrac{1}{1296}[/tex]
