Text Solution

AI Generated Solution

To find the probability of the event not A, we can follow these steps: ### Step 1: Understand the given probability We are given that the probability of event A, denoted as P(A), is \( \frac{2}{11} \). ### Step 2: Use the complementary probability rule The probability of the event not A, denoted as P(not A), can be found using the complementary rule of probability. This rule states that: \[ ...
