We need to simplify this expression:
So, we will call this expression as:
We can write this equation like this:
So, if we simplify it, this can be written like this:
f(x) = 4 but given that the denominator can't be zero, then:
∴ 
Therefore:
f(x) = 4 if and only if

Answer:
20
Step-by-step explanation:
Assume n is the number of times she pick a skittle out of the bag
The probability she pick out red : 8/n
The probability she pick out yellow : 12/n
=> The ratio of red and yellow skittle : 8/n : 12/n = 8/12 = 2/3, means every 2 red skittles we have 3 yellow ones.
But we have 50 skittles, so the likely numbers of reds in the bag is = 2* = 20
