chech whether 7/6 can be an empirical probability or not. give reasons.

Suppose we perform an experiment and let n be the total number of trials.
The empirical probability of happening of an event E is defined as 
P(E) = $\frac{number of trials in which the event happened}{total number of trials}$
Now from the definition it is clear that P(E) $\le 1$ since total number of trials is always greater or equal to the number of trials in which the event happened

Hence $\frac{7}{6}$ cannot be an empirical probability since number of trials in which the event happened cannot exceed the total number of trials

Note:- Empirical probability cannot be greater than 1
