Answer:
.
Step-by-step explanation:
For function , the notation
means that when the input to the function is
, the output would be
.
The inverse function of a one-to-one function is commonly denoted as
.
The inverse function undoes the action of the original function. In this question, maps
to
. Thus,
would need to map
back to
. Therefore,
should be the corresponding input and output values.
If we will roll a fair die then the outcomes wil be 1,2,3,4,5,6.
Hence, the total number of events= 6
3,4,5 and 6 are greater than 2.
So, there's 4 events which are greater than 2.
Now the formula to find the probability is:
probability=
=
=
So, the probability of getting greater than a 2 is 2/3.
