Solution Steps

To solve the equation \(12 = 4 - n\), we need to isolate the variable \(n\). We can do this by performing algebraic operations to both sides of the equation to solve for \(n\).

Solution Approach
  1. Subtract 4 from both sides of the equation to isolate the term with \(n\).
  2. Multiply both sides by -1 to solve for \(n\).
Step 1: Subtract 4 from both sides

Starting with the equation: \[ 12 = 4 - n \]

Subtract 4 from both sides: \[ 12 - 4 = 4 - n - 4 \]

This simplifies to: \[ 8 = -n \]

Step 2: Multiply both sides by -1

To isolate \( n \), multiply both sides by -1: \[ -1 \cdot 8 = -1 \cdot (-n) \]

This simplifies to: \[ -8 = n \]

Final Answer

The value of \( n \) is: \[ \boxed{n = -8} \]

The probability of getting a male and getting someone with blue eyes C. The probability of getting someone with blue eyes, given that a male has been selected D. The probability of getting a male or getting someone with blue eyes Is P(M B) the same as P(B M)? A. Yes, because P(B M) represents the probability of getting someone with blue eyes, given that a male has been selected B. Yes, because P(B M) represents the probability of getting a male, given that someone with blue eyes has been selected C. No, because P(B M) represents the probability of getting a male, given that someone with blue eyes has been selected D. No, because P(B M) represents the probability of getting someone with blue eyes, given that a male has been selected
