Answer:
(-∞, ∞)
Step-by-step explanation:
Given,

Then (fºg)(x) would be ,

Since this is a polynomial, we know domain of a polynomial is all real number.
Therefore the domain of this (fºg)(x) is (-∞, ∞).
Answer:

Step-by-step explanation:
Sample space is a set of possible outcomes of a random experiment.
A random experiment is an experiment whose outcomes can not be predicted.
Number of red balls = 6
Number of green ball = 1
Number of blue ball = 1
Let R denotes red ball, B denotes blue ball and G denotes green ball.
Sample space =
