Answer:
Yes, it could be a probability
Step-by-step explanation:
The probability of an event HAS to be between the numbers 0 and 1. Not less than 0, not greater than 1. The number 0.12 is between 0 and 1, thus, making it a valid probability.
-π/2 < arctan(x) < π/2
So cos(π/2) < cos(arctan(x)) < cos(0)
0 < cos(arctan(x)) < 1

change the mixed numbers to improper fractions and multiply the numerators / denominators
