### 1. Break Down the Problem
We need to find $ P(r \leq 2) $ using the value of $ P(r \geq 3) $ that we found in part (c).

### 2. Relevant Concepts
The relationship between the probabilities is:
$$
P(r \leq 2) + P(r \geq 3) = 1
$$

### 3. Analysis and Detail
Given:
$$
P(r \geq 3) = 0.942
$$
We can use the concept above to find $ P(r \leq 2) $:
$$
P(r \leq 2) = 1 - P(r \geq 3)
$$

### 4. Verify and Summarize
Substituting the known value:
$$
P(r \leq 2) = 1 - 0.942 = 0.058
$$

### Final Answer
Thus, $ P(r \leq 2) = 0.058 $.

In part (c) we found P(r ≥ 3) = 0.942. Use this value to calculate P(r ≤ 2).P(r ≤ 2) = 1 − P(r ≥ 3) = 1 −
