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

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

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

Substituting the known value: $P(r \leq 2) = 1 - 0.942 = 0.058$

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