Yes, 2 ≤ x ≤ 5 is an inequality.
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols. When the symbols ">","≤", "≥" or "<" are used to connect two real numbers or algebraic expressions, the relationship is referred to as an inequality.
Following above literature and considering the fact that 5 is always greater than 2 and 2 is always lesser than 5, the given relation can be identified as an inequality.

Answer:
The probability of getting exactly two read marbles is P = 0,003456%
Step-by-step explanation:
So, each of the following sequences are the desired results(I will use R for a red marble and G for a green marble).
S(1) = R-R-G-G
S(2) = R-G-R-G
S(3) = R-G-G-R
S(4) = G-R-R-G
S(5) = G-R-G-R
S(6) = G-G-R-R
In all, considering there are replacement, there can be 10*10*10*10 = 10000 total sequences, so the probability of getting exactly two read marbles is
P = \frac{P(S(1)) + P(S(2)) + P(S(3)) + P(S(4)) + P(S(5)) + P(S(6))}{10000}
where
P(S(1)) = P(S(2)) = P(S(3)) = P(S(4)) = P(S(5)) = P(S(6)) = (0.4)^{2}*(0.6)^{2} = 0.16*0.36 = 0.0576.
The probability of getting exactly two read marbles is
P = \frac{6*0.0576}{10000} = 0,003456%
