To determine the value of \( P(A \mid B) \), we need to use the definition of conditional probability. The formula for conditional probability is:<br /><br />\[ P(A \mid B) = \frac{P(A \cap B)}{P(B)} \]<br /><br />Since events A and B are independent, the probability of their intersection (both events happening) is the product of their individual probabilities:<br /><br />\[ P(A \cap B) = P(A) \times P(B) \]<br /><br />Given:<br />\[ P(A) = 0.7 \]<br />\[ P(B) = 0.46 \]<br /><br />We can calculate \( P(A \cap B) \):<br /><br />\[ P(A \cap B) = 0.7 \times 0.46 = 0.322 \]<br /><br />Now, we can find \( P(A \mid B) \):<br /><br />\[ P(A \mid B) = \frac{P(A \cap B)}{P(B)} = \frac{0.322}{0.46} \approx 0.700 \]<br /><br />Therefore, the value of \( P(A \mid B) \) is approximately 0.700, rounded to the nearest thousandth.
