(f+g)(3)=f(3)+g(3)
f(x)=7 so f(3)=7
g(x)=x+5 so g(3)=3+5=8
(f+g)(3)=f(3)+g(3)=7+8=15
You have some unknown integer
, and you know that adding this and the next two integers,
and
, gives a total of 57.
This means
The task is to find all three unknown integers. Notice that if you know the value of
, then you pretty much know the value of the other three integers.
To find
, solve the equation above:
So if 18 is the first integer, then others must be 19 and 20.
Assuming 0 and 100 are included in the possible choices:
There are
multiples of 7 between 0 and 100, so there is a
probability of choosing a multiple of 7.
