Answer:
52 times
Step-by-step explanation:
Given
[tex]n = 78[/tex] -- Number of times
Required
Determine the expected times to get > 2.
In a fair dice, the outcome > 2 are:
[tex]>2 = \{3,4,5,6\}[/tex]
The probability of the above is:
[tex]p = \frac{4}{6}[/tex]
[tex]p = \frac{2}{3}[/tex]
The number of times is calculated using:
[tex]E(x) = n * p[/tex]
[tex]E(x) = 78* \frac{2}{3}[/tex]
[tex]E(x) = \frac{78* 2}{3}[/tex]
[tex]E(x) = \frac{156}{3}[/tex]
[tex]E(x) = 52[/tex]
