Take note that probability is a measure/estimate that an event is likely to happen. To compute, apply the formula:

               number of favorable outcomes

P(A) =  -------------------------------------------

             total number of possible outcomes 

From 110 to 199, there are a total of 90 numbers present (see attached). Among the numbers present, only four of them have perfect square factors. These are:

`11^2 = 121`

`12^2=144`

`13^2=169`

`14^2=196`

This means that there are 86 numbers that are not prefect squares.

So out of 90 possible outcomes, there are 86 favorable outcomes in getting a number that is not a perfect square.

Applying the formula above, it will yield:

`P(A)= 86/90=43/45`

Therefore, the probability that the number selected is not a perfect square is `43/45` .
