Sophia and her teammates are each chewing a piece of tropical flavored gum before their championship softball game. 58% of the pieces are pineapple flavored. If 2 of her teammates are chosen at random, what is the probability that exactly 2 are chewing pineapple gum? Write your answer as a decimal rounded to the nearest thousandth. ____

Use Binomial Probability Formula: Use the binomial probability formula: P(X = k) = C(n, k) * (p)^k * (1-p)^(n-k). Here, n = 2, k = 2, and p = 0.58.Calculate Combination: Calculate C(2, 2) = 2! / 2! (2 - 2)! = 1.Calculate (0.58)^2: Solve (0.58)^2 = 0.58 * 0.58 = 0.3364.Simplify (1 - 0.58)^(2 - 2): Simplify (1 - 0.58)^(2 - 2) = (0.42)^0 = 1.Multiply Values and Round: Multiply all the values together: P(X = 2) = 1 * 0.3364 * 1 = 0.3364. Round to the nearest thousandth: 0.336.

Use Binomial Probability Formula: Use the binomial probability formula: $P(X = k) = C(n, k) \cdot (p)^k \cdot (1-p)^{(n-k)}$ . Here, $n = 2$ , $k = 2$ , and $p = 0.58$ .
Calculate Combination: Calculate $C(2, 2) = \frac{2!}{2!(2 - 2)!} = 1$ .
Calculate $(0.58)^2$ : Solve $(0.58)^2 = 0.58 \times 0.58 = 0.3364$ .
Simplify $(1 - 0.58)^{(2 - 2)}$ : Simplify $(1 - 0.58)^{(2 - 2)} = (0.42)^0 = 1$ .
Multiply Values and Round: Multiply all the values together: $P(X = 2) = 1 \times 0.3364 \times 1 = 0.3364$ . Round to the nearest thousandth: $0.336$ .
