Solution

Solution Steps

Step 1: Understand the Problem

Given that $A$ and $B$ are independent events, we need to find the probability of event $B$ , denoted as $P(B)$ . We are given the probability of event $A$ occurring, $P(A)$ , and the probability of both $A$ and $B$ occurring together, $P(A$ AND $B)$ .

Step 2: Apply the Formula for Independent Events

For independent events, the probability of both events occurring together is the product of their individual probabilities. Thus, $P(A$ AND $B) = P(A) \times P(B)$ . Given $P(A)$ and $P(A$ AND $B)$ , we can rearrange the formula to solve for $P(B)$ : $P(B) = \frac{P(A \text{ AND } B)}{P(A)}$

Step 3: Substitute the Given Values and Calculate

Substituting the given values, $P(A) = 0.6$ and $P(A$ AND $B) = 0.3$ , into the formula, we get: $P(B) = \frac{0.3}{0.6}$ After calculation, $P(B) = 0.5$ , rounded to 2 decimal places.
